• Effects of Noise and Vibration Due to the Hokuriku Shinkansen Railway on the Living Environment: A Socio-Acoustic Survey One Year after the Opening　　　　　　　　　　　　　　　
  Takashi Morihara; Shigenori Yokoshima; Yasunao Matsumoto
  INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH, Volume：18, Number：15, Aug. 2021, [Reviewed]
  One year after the opening of the Hokuriku Shinkansen (high-speed) railway, in 2016, we conducted a social survey targeting the residents of detached houses along the rail. Noise and vibration exposure levels were estimated at outdoor points closest to the noise source side of the houses. Of the 1980 people contacted, there were 1022 valid respondents. The purpose of this research was to investigate the relationship between noise and vibration exposure and community responses. The results demonstrated that the noise annoyance and daily activity disturbances of residents living in areas without a conventional railway are higher than those of residents living in areas running parallel to a conventional railway line. This tendency was remarkable, especially for areas with high vibration exposure caused by the Shinkansen railway. There was no difference between before and after the opening of the Shinkansen railway in the evaluation of housing satisfaction, or regarding the preference for the residential area and quietness around the house. However, since the survey before the opening was conducted only in the Ishikawa site, it will be necessary to conduct before-and-after surveys in areas where there are no conventional railways, and where the speed of the Shinkansen is fast.

  Two laboratory experiments were conducted to investigate the combined effect of Shinkansen (high-speed) railway noise and vibration on daily life. In Experiment 1, stimuli noise and vibration recorded outdoors were used, and in Experiment 2, those recorded indoors were used. Twenty participants were exposed to 18 stimuli comprising 9 pairs of noise and vibration in Experiment 1, whereas 20 different participants were exposed to 22 stimuli comprising 11 such pairs in Experiment 2. The results indicated that there was significant activity disturbance from the combined effect of noise and vibration; however, the influence of vibration stimuli at 65 dB or less did not disturb reading.

Noise and vibration exposure level were estimated at outdoor points closest to the noise source side of the house. Of the 1,980 people contacted, there were 1,022 valid respondents. The purpose of this research is to investigate the relationship between noise and vibration exposure and social responses. Regarding the noise annoyance and some living activity disturbances, it was shown that the responses of residents living in areas without the conventional railway are higher than those in areas running parallel to conventional railway. This tendency was remarkable especially in areas with high vibration exposure caused by Shinkansen railway. High vibration annoyance was shown in areas without the conventional railway, while there was no difference by the degree of the noise exposure.

  Vibrations induced by road traffic and railways have caused regional environmental problems in Japan where it is common that small-scale buildings for residential use are located beside roads and railways with high traffic volume. An investigation was conducted to understand the relationship between traffic-induced vibrations inside and outside of building and annoyance response of building residents. Vibration measurements were made at seven residential buildings located beside roads and railways. Those buildings were single-family houses, which were two- or three-story wooden buildings. Acceleration time histories were recorded at three locations inside and outside of buildings to understand the vibration occurring in those buildings and the dynamic characteristics of the buildings. The buildings for measurement were selected from the houses of respondents in a separate questionnaire survey on vibration annoyance. The annoyance responses obtained in the questionnaire survey were compared with the results of vibration measurements and metrics available in the international standards. Subjective responses measured in a separate laboratory experimental study were also compared with the vibration evaluation determined from vibration measurements and the annoyance responses in the questionnaire survey.

  Proceedings of the International Congress on Acoustics, Volume：2019-, First page：3637, Last page：3642, 2019
  The purpose of this study was to examine the evaluation method based on subjective responses to vibration caused by external vibration source including road traffic and railroads for building habitability. The target buildings were small-scale buildings, such as detached houses in Japan whose main structure was wooden or steel frame. The first natural frequency of vibration mode of those building which has dominant horizontal vibration has been known to be in the range from 4Hz to 8Hz. Horizontal vibrations at the ground in that frequency range can be amplified due to the dynamic characteristics of buildings. An experiment involving human subjects were conducted to investigate relationship between subjective responses and evaluation value computed from vibration acceleration time histories. The input stimuli consisted of sinusoidal vibrations at 4Hz and 8Hz for several different durations and vibrations based on building vibrations measured in actual residential buildings. 7-step evaluation scales composed of expressions to provide equal psychological intensity intervals about magnitude, concern and discomfort were used to measure subjective responses in the experiment. It was found that Vibration Dose Value, VDV, which evaluated the effect of vibration duration by the 1/4 power, with Wd frequency weighting was most appropriate among the evaluation methods used in this study.

• Combined effect of vibrations on railway noise annoyance　　　　　　　　　　　　　　　
  Shigenori Yokoshima; Takashi Morihara; Yasunao Matsumoto
  Proceedings of the International Congress on Acoustics, Volume：2019-, First page：3631, Last page：3636, 2019
  In Japan, annoyance due to noise from the high-speed “Shinkansen” railways is more annoying than that from conventional railways, as reported in the previous study. The reasons for the difference have been explored mainly from psychological point of view. A previous comparison survey along the Shinkansen and conventional railways found that inhabitants living along the Shinkansen railways had negative attitudes to the noise. Therefore, no recognition of necessity of noise from the Shinkansen railways was considered tR bring about higher annoyance than that from conventional railways. In addition, the combined effect of noise and ground-borne vibrations from the Shinkansen railways on annoyance could increase higher annoyance. However, each effect of ground borne vibrations as well as negative attitudes on noise annoyance has not been quantitatively evaluated. We performed a secondary analysis using individual datasets, exposures and annoyance associated with noise and ground-borne vibrations from the railways, derived from the previous twelve surveys. Applying a multiple logistic regression analysis to the datasets, we quantitatively provided the effects of negative attitudes and ground-borne vibrations on noise annoyance.

• Vibration-Based Health Monitoring of an Existing Truss Bridge Using Energy-Based Damping Evaluation　　　　　　　　　　　　　　　
  Samim Mustafa; Yasunao Matsumoto; Hiroki Yamaguchi
  JOURNAL OF BRIDGE ENGINEERING, Volume：23, Number：1, Jan. 2018, [Reviewed]
  This paper proposes an analytical framework for vibration-based structural health monitoring (SHM) by introducing an energy-based damping evaluation (EBDE). The damage detection by the proposed EBDE was carried out by estimating the contribution of modal damping ratios from different structural elements utilizing experimentally identified modal damping ratios, and estimating modal strain and modal potential energies from an updated finite-element (FE) model of the structure under consideration. Model updating was performed using modal frequencies and mode shapes that are generally not sensitive to local damage. The advantage of using damping as a damage indicator is that the damping change in global modes affected by the local damage can be identified with a small number of sensors. A previous study reported that the studied bridge with damage at the local diagonal member showed a significant increase in the damping of global vibration mode of the structure. The present study utilized the EBDE to identify the cause of the modal damping increase by observing the change in the contribution from different structural elements on the modal damping ratios.

• Bayesian Model Updating and Its Limitations for Detecting Local Damage of an Existing Truss Bridge　　　　　　　　　　　　　　　
  Samim Mustafa; Yasunao Matsumoto
  JOURNAL OF BRIDGE ENGINEERING, Volume：22, Number：7, Jul. 2017, [Reviewed]
  An efficient and robust Bayesian model updating is presented in this paper from the viewpoint of practical application by introducing a new objective function and a realistic parameterization of the mass and stiffness matrices. In this framework, the likelihood function for mode shapes is formulated based on the cosine of the angle between the analytical and measured mode shapes, which does not require any scaling or normalization. For the parameterization of the stiffness matrix, the framework uses element-level parameterization because it is evident from practical experience that different parts of the structure are subjected to different levels of deterioration as a result of corrosion and fatigue. The proposed updating method was validated experimentally by updating a finite-element model (FEM) of an existing steel truss bridge that utilized the vibration data obtained from a car-running test. The damage-detection capability of the proposed model-updating framework was then investigated by considering the data from a simulated damaged bridge and the experimental data from a damaged span of the same bridge with partial fractures on one of the diagonal members.

  This experimental study was carried out to examine the combined effects of high-speed (Shinkansen) railway noise and vibrations on activity disturbances. Participants were ten women and ten men (18-22 years) with normal hearing ability. The Shinkansen railway noise and vibrations used as stimuli were recorded near the Hokuriku Shinkansen railway. The audio stimuli had LAmax values of 50, 60, and 70 dB, whereas the vibration stimuli had three types (none, intermediate, and high) of vertical vibrations. The participants were exposed to these combined stimuli while they engaged in 30-second activity tasks (reading and thinking). The results indicated that there were significant differences in subjects' evaluations of vibration cognition between all of the vibration stimuli during the reading task. In contrast, during the thinking task, we observed no differences between the none and intermediate vibration conditions in the 60 and 70 dB conditions. We observed significant differences in evaluations of activity disturbance between the none and high vibration conditions in the 50 and 60 dB conditions during the reading task and between the none and intermediate or high vibration conditions in the 50 dB condition during the thinking task.

  JOURNAL OF BRIDGE ENGINEERING, Volume：20, Number：7, Jul. 2015, [Reviewed]
  Structural health monitoring (SHM) of bridges by visual inspection is not necessarily reliable as many damages are not discovered during the periodic inspection of bridges. A technique to assist in visual inspection is vibration-based SHM. It is believed that structural damages lead to changes in stiffness and damping properties, and change the dynamic characteristics of structures, such as natural frequency, mode shape, and modal damping ratio. Although changes in the modal damping ratio can be used as damage indicators in the field of vibration-based SHM, the method's accuracy remains concerning. This study investigated the analytical modal damping evaluation as a complementary method to the experimental SHM of bridges. An energy-based damping model was introduced to estimate the damping parameters of a steel arch bridge, such as the equivalent loss factors of structural components, and the modal damping ratios of the bridge were then analytically evaluated using the damping parameters. The results confirmed that the proposed methodology can identify the damping sources in steel bridges and their contributions to each modal damping ratio, and complements the experimental SHM of bridges.

  Structural health monitoring of steel truss bridge based on changes in modal properties was investigated in this study. Vibration measurements with five sensors were conducted at an existing Warren truss bridge with partial fractures in diagonal members before and after an emergency repair work. Modal properties identified by the Eigensystem Realization Algorithm showed evidences of increases in modal damping due to the damage in diagonal member. In order to understand the dynamic behavior of the bridge and possible mechanism of those increases in modal damping, theoretical modal analysis was conducted with three dimensional frame models. It was found that vibrations of the main truss could be coupled internally with local vibrations of diagonal members and the degree of coupling could change with structural changes in diagonal members. Additional vibration measurements with fifteen sensors were then conducted so as to understand the consistency of those theoretical findings with the actual dynamic behavior. Modal properties experimentally identified showed that the damping change caused by the damage in diagonal member described above could have occurred in a diagonal-coupled mode. The results in this study imply that damages in diagonal members could be detected from changes in modal damping of diagonal-coupled modes.

  In the assessment of vibration in residential environments, human perception of vibration is an important factor, as stated in, for example, ISO 2631-2. For the evaluation of the effect of vibration on people in residential environments, there have been different standardised evaluation methods defined in the current international and national standards. This paper describes an investigation of the applicability of those current standardised evaluation methods to the determination of vibration perception thresholds measured in a laboratory experiment involving human subjects. The characteristics of input vibration used in the experiment were determined based on field vibration records obtained in Japanese single-family houses with vibration sources outside of them. Some principal current standardised evaluation methods were applied to determine the perception thresholds of those input vibrations with different time and frequency characteristics. An evaluation method developed from the results of previous investigation was applied also to determine the thresholds. The effects of frequency weighting and integration methods for running averaging were discussed. Copyright© (2013) by Austrian Noise Abatement Association (OAL).

• The horizontal apparent mass of the standing human body

  JOURNAL OF SOUND AND VIBRATION, Volume：330, Number：13, First page：3284, Last page：3297, Jun. 2011, [Reviewed]
  The driving-point dynamic responses of standing people (e.g. their mechanical impedance or apparent mass) influence their dynamic interactions with structures on which they are supported. The apparent mass of the standing body has been reported previously for vertical excitation but not for lateral or fore-and-aft excitation. Twelve standing male subjects were exposed to fore-and-aft and lateral random vibration over the frequency range 0.1-5.0 Hz for 180 s at four vibration magnitudes: 0.016, 0.0315, 0.063, and 0.125 m s(-2) rms. With lateral excitation at 0.063 m s(-2) rms, subjects also stood with three separations of the feet. The dynamic forces measured at the driving-point in each of the three translational axes (i.e. fore-and-aft, lateral and vertical) showed components not linearly related to the input vibration, and not seen in previous studies with standing subjects exposed to vertical vibration or seated subjects exposed to vertical or horizontal vibration. A principal peak in the lateral apparent mass around 0.5 Hz tended to decrease in both frequency and magnitude with increasing magnitude of vibration and increase with increasing separation of the feet. The fore-and-aft apparent mass appeared to peak at a frequency lower than the lowest frequency used in the study. (C) 2011 Elsevier Ltd. All rights reserved.

  Some factors that may affect human perception thresholds of the vertical whole-body vibrations were investigated in two laboratory experiments with recumbent subjects. In the first experiment, the effects of gender and age of subjects on perception were investigated with three groups of 12 subjects, i.e., young males, young females and old males. For continuous sinusoidal vibrations at 2, 4, 8, 16, 31.5 and 63 Hz, there were no significant differences in the perception thresholds between male and female subjects, while the thresholds of young subjects tended to be significantly lower than the thresholds of old subjects. In the second experiment, the effect of vibration duration was investigated by using sinusoidal vibrations, at the same frequencies as above, modulated by the Hanning windows with different lengths (i.e., 0.5, 1.0, 2.0 and 4.0 s) for 12 subjects. It was found that the peak acceleration at the threshold tended to decrease with increasing duration of vibration. The perception thresholds were also evaluated by the running root-mean-square (rms) acceleration and the fourth power acceleration method defined in the current standards. The differences in the threshold of the transient vibrations for different durations were less with the fourth power acceleration method. Additionally, the effect of the integration time on the threshold was investigated for the running rms acceleration and the fourth power acceleration. It was found that the integration time that yielded less differences in the threshold of vibrations for different durations depended on the frequency of vibration. (C) 2010 Elsevier Ltd.

  This article examines about a possibility of the damage assessment of truss diagonal members by using local higher modes. Firstly, the local vibration characteristics of diagonal member were analyzed by FEM eigenvalue analysis. Through the analysis, the natural modes of the diagonal member were classified roughly as bending modes of in-plane and out-plane direction of the truss, torsional modes and plate modes of the flange and web. The mode dependence of frequency changes caused by a damage in the diagonal member was also confirmed in the analysis with the damage model. Secondly, healthy and corroded diagonal members with same specifications were examined by the hammering test on site. As a result, it was concluded that the decreases in the natural frequencies of higher modes are prominent enough to assess the corrosion. (C) 2011 Published by Elsevier Ltd.

  Noise generated from modular bridge expansion joints during vehicle pass-bys has caused localized environmental problems in Japan and elsewhere. The objective of this study was to understand the mechanism of noise generation and radiation from a modular expansion joint installed in an expressway bridge. A numerical investigation was conducted in order to understand the dynamic characteristics of the joint and the acoustic characteristics of the sound field around the joint that measurements cannot reveal due to their limitations, such as the number of measurement locations that are required. Vibro-acoustic analysis was conducted by using the finite element method-boundary element method (FEM-BEM) approach: dynamic analysis of the joint was carried out by FEM and the sound fields inside the cavity located beneath the joint and outside of the cavity were analyzed by BEM. It was concluded that dominant frequency components in the sound pressure inside the cavity were due to excitation of the structural modes of the joint and/or acoustic modes of the cavity. For the expansion joint investigated, the sound field farther than about 35 m from the joint-cavity center could be considered as far field in the range of 50-400 Hz. (C) 2009 Elsevier Ltd.

  The effect of the magnitude of fore-and-aft and lateral vibration on the subjective and mechanical responses of seated subjects has been investigated experimentally using simultaneous measurements of relative discomfort and apparent mass. Twelve male subjects were exposed to sinusoidal vibration at nine frequencies (between 1.6 and 10 Hz) at four magnitudes (in the range 0.125-1.0 m s(-2) r.m.s.) in both horizontal directions (fore-and-aft and lateral). The method of magnitude estimation was used to estimate discomfort relative to that caused by a 4Hz reference vibration in the same axis. The apparent mass was calculated from the acceleration and the applied force so as to quantify the mechanical response of the body. With each direction of excitation, the apparent mass was normalised by dividing it by the apparent mass obtained at 4 Hz, so that the mechanical responses could be compared with the subjective responses.
  The relative discomfort and the normalised apparent mass were similarly affected by the frequency and magnitude of vibration, with significant correlations between the relative discomfort and the normalised apparent mass. The results indicate that the discomfort caused by horizontal whole-body vibration is associated with the apparent mass in a frequency range where motion of the whole body is dominant. In this frequency range, the nonlinear subjective responses may be attributed, at least in part, to the nonlinear dynamic responses to horizontal whole-body vibration. (C) 2008 Elsevier Ltd.

  Noises generated from modular bridge expansion joints during vehicle pass-bys have been causing local environmental problems recently. Previous experimental studies showed that possible causes of dominant noise components generated from the bottom side of the joint might be different from those from the top side. The objective of this study was to obtain theoretical insights into the mechanism of noise generation from the bottom side of the joint for which a main noise source might be structural vibration of the joint. Vibro-acoustic analysis was conducted based on the information from a full-scale model of modular expansion joint obtained in previous experimental studies. The dynamic behavior of the joint model was investigated by using the finite element method (FEM) and the sound field inside the cavity located beneath the joint model was analyzed by using the boundary element method (BEM). Indirect BEM was used to calculate the sound pressure inside the cavity with the velocity response obtained by the FE analysis as a boundary condition. The frequency range considered in the analysis was 20-400 Hz where dominant frequency components were observed in the noise measured in the cavity beneath the joint in the previous experiment. It was intended to interpret numerical results obtained by a model developed with available mechanical properties of the joint components to seek a general understanding of the noise generation mechanism of the modular expansion joint. It was observed that the peaks in the spectrum of noise inside the cavity were due to resonances of structural vibration modes of the joint and/or resonances of acoustic modes of the cavity. There was evidence that showed possible interaction between structural modes of the joint and the acoustic modes of the cavity. (c) 2008 Institute of Noise Control Engineering.

  Lumped parameter mathematical models representing anatomical parts of the human body have been developed to represent body motions associated with resonances of the vertical apparent mass and the fore-and-aft cross-axis apparent mass of the human body standing in five different postures: 'upright', 'lordotic', 'anterior lean', 'knees bent', and 'knees more bent'. The inertial and geometric parameters of the models were determined from published anthropometric data. Stiffness and damping parameters were obtained by comparing model responses with experimental data obtained previously. The principal resonance of the vertical apparent mass, and the first peak in the fore-and-aft cross-axis apparent mass, of the standing body in an upright posture (at 5-6 Hz) corresponded to vertical motion of the viscera in phase with the vertical motion of the entire body due to deformation of the tissues at the soles of the feet, with pitch motion of the pelvis out of phase with pitch motion of the upper body above the pelvis. Upward motion of the body was in phase with the forward pitch motion of the pelvis. Changing the posture of the upper body had minor effects on the mode associated with the principal resonances of the apparent mass and cross-axis apparent mass, but the mode changed significantly with bending of the legs. In legs-bent postures, the principal resonance (at about 3 Hz) was attributed to bending of the legs coupled with pitch motion of the pelvis in phase with pitch motion of the upper body. In this mode, extension of the legs was in phase with the forward pitch motion of the upper body and the upward vertical motion of the viscera. (c) 2008 Elsevier Ltd. All rights

  The mechanism for the generation of noise from a modular expansion joint in a bridge under vehicle passage, which can cause an environmental problem, is investigated in experiments on a full-scale model of the joint. Noise and vibration characteristics of the joint model in the near field are identified by a series of car-running experiments associated with separate tests of the acoustic and dynamic characteristics of the joint. A modal analysis based on finite element modelling of the joint is also conducted and structure-borne noise radiation is discussed by correlating the dominant frequency components of the noise with the modal parameters. It is concluded that the noise from the top of the joint, dominant in the frequency range from 500 to 800 Hz, is caused by a sudden change in the pressure of air within the gap formed by the rubber sealing with two adjacent middle beams, and that the noise from the bottom, dominant in the frequency range below 200 Hz, is attributed mainly to sound radiation from the vibration of the middle beams.

  Noises generated from modular bridge expansion joints during vehicle passages have been causing environmental problems recently in Japan. The objective of this study was to investigate the mechanism of noise generation from the joint by carrying out vibro-acoustic analysis of a full scale test model of modular expansion joint. Numerical analysis of the dynamic behavior of the joint model was conducted by using the finite element method and the boundary element method was used to analyze sound field inside a cavity located below the joint model. Velocity response of the joint was calculated by applying point loads at the locations where dynamic loads might be applied during vehicle passage. Acoustic modal analysis of the cavity below the joint model was carried out by using FEM also. Indirect Boundary element method was then applied to calculate the sound pressure inside the cavity by using the velocity response obtained by the FEM analysis as a boundary condition. The frequency range considered for the analysis was 20-400 Hz. The numerical results were compared with experimental results obtained from impact testing. It was shown that the peaks in the spectrum of noise inside the cavity was due to either resonances of structural member of the joint and/or resonances of acoustic modes of the cavity. The interaction of structural modes of the joint with the acoustic modes of the cavity was observed.

  The mechanism of noise generation and noise control for modular expansion joints were investigated in experiments on a full-scale model of the joint. Noise and vibration of the joint model were measured when a car was runnig over the model. It was concluded, based on this measurement together with tests of the acoustic and dynamic characteristics of the joint model, that the noise from the top of the joint could be attributed to a sudden change in the air pressure in the gaps formed by the sealing rubber elements, and the noise from the bottom was probably caused by sound radiation from vibration of the middle beams. Effects of some proposed noise control measures were also investigated experimentally.

• Dynamic and subjective responses of seated subjects exposed to simultaneous vertical and fore-and-aft whole-body vibration: The effect of the phase between the two single-axis components

  Subjective and dynamic responses of seated subjects exposed to simultaneous vertical and fore-and-aft sinusoidal whole-body vibration were investigated. The effect of the phase difference between the vertical and the fore-and-aft vibration on the responses was of a particular interest in this study. Fifteen subjects were exposed to dual-axis vibrations at six frequencies (2.5-8 Hz) and at eight phases between the two single-axis components (0-315 degrees). The magnitude of vibration in each axis was constant at 0.7 M s(-2) rms. Discomfort caused by vibration was measured by the method of magnitude estimation. The motion of the body were measured at the head and three locations along the spine with accelerometers attached to the body surface. The most significant effect of the phase between the two single-axis components on the discomfort was observed at 5 Hz: about 40% difference in the median discomfort estimate caused by changing the phase. The transmissibilities from vertical seat vibration to vertical motions of the spine varied from 0.5 to 2.0 by changing the phase between the two single-axis components at frequencies from 2.5 to 5 Hz. The effect of the phase observed in the dynamic response was not predicted by the superposition of the responses to each single-axis vibration. The discomfort caused by the dual-axis vibration tended to be correlated better with the combinations of the dynamic responses measured in the two axes than with the dynamic responses in a single axis.

  The effects of posture and vibration magnitude on the vertical apparent mass and the fore-and-aft cross-axis apparent mass of the standing human body during exposure to vertical vibration have been investigated. Twelve male subjects were exposed to random vertical vibration over the frequency range 2.0-20 Hz at three vibration magnitudes: 0.125, 0.25 and 0.5 m s(-2) rms. Subjects stood in five different postures: upright, lordotic, anterior lean, knees bent and knees more bent. The vertical acceleration at the floor and the forces in the vertical and fore-and-aft directions at the floor were used to obtain the apparent mass and the cross-axis apparent mass.
  The resonance frequency of the apparent mass was significantly reduced with knees bent and knees more bent postures, but there were only minor effects on the resonance frequency by changing the position of the upper body. Considerable cross-axis apparent mass, up to about 30% of the static mass of subjects, was found. The cross-axis apparent mass was influenced by all postural changes used in the study. In all postures the resonance frequencies of the apparent mass and the cross-axis apparent mass tended to decrease with increasing vibration magnitude. This nonlinear characteristic tended to be less clear in some postures in which subjects increased muscle tension. (c) 2005 Elsevier Ltd. All rights reserved.

  Perception thresholds of complex sounds consisting of two frequency components in the low frequency range were investigated experimentally so as to obtain a better understanding of the mechanism of human perception of low frequency noise. Influences of subthreshold frequency component at 25 Hz at a fixed sound pressure level on the perception were investigated by determining the level of another frequency component at the thresholds. The frequencies of sound components used in the experiment were 12.5, 16, 20, 31.5, 40 and 50 Hz. The sound pressure level of the subthreshold component at 25 Hz was fixed at 3, 5, 6, or 10 dB below the perception threshold of pure tone for each subject. It was found that, when the subject was exposed to a frequency component along with a subthreshold component, the sound pressure level of the frequency component of interest at the perception threshold tended to be lower than the threshold of pure tone at the same frequency. This influence was more clearly observed when the sound pressure level of the subthreshold component was greater and also when the separation between the frequencies of two sound components was less.

• Nonlinear subjective and biodynamic responses to continuous and transient whole-body vibration in the vertical direction

  JOURNAL OF SOUND AND VIBRATION, Volume：287, Number：4-5, First page：919, Last page：937, Nov. 2005
  The effect of the magnitude of continuous and transient whole-body vibration in the vertical direction on both subjective and biodynamic responses of human subjects has been investigated experimentally. Additionally, the relation between the subjective responses and the dynamic responses has also been studied. Twelve subjects were exposed to sinusoidal continuous vibrations at five frequencies (3.15-8.0 Hz) and at three magnitudes (0.5-2.0 m s(-2) rms). They were also exposed to transient vibrations that were modulated one-and-half cycle sinusoidal waveforms at the same frequencies as the continuous vibrations and at three magnitudes corresponding to the magnitudes used for the continuous vibrations. Discomfort was measured by the method of magnitude estimation with reference stimuli having frequency components in the middle of the frequency range used in this study. The driving-point dynamic responses (the ratio between the force and the motion, i.e., acceleration and velocity, at the driving point) were also measured and divided by the responses to the reference stimuli used in the measurement of discomfort so as to allow the comparison of the dynamic responses with the discomfort responses. Both the discomfort estimates and the normalised driving-point dynamic responses were influenced by the stimuli magnitudes, especially with the continuous vibration. At 3.15 and 4.OHz, the discomfort estimates and the normalised mechanical impedance and apparent mass increased significantly with increases in vibration magnitude from 0.5-2.0 in s(-2) rms. Magnitude estimates for discomfort were correlated with the normalised mechanical impedance and apparent mass in the frequency range investigated. For the transient vibrations, the discomfort estimates and the driving-point dynamic responses were interpreted as responses in frequency bands around the fundamental frequency of the input motion. The results indicate similar nonlinearities in discomfort and driving-point dynamic responses associated with the principal body response within the range 3.15-8 Hz. The nonlinearity in discomfort at these frequencies may be partially caused by the nonlinear dynamic response of the body and is sufficient to require consideration in methods of predicting discomfort caused by vertical whole-body vibration.

  Annoyance of low frequency pure and combined tones was measured in a laboratory exper iment. Three low frequency tones at frequencies of 31.5,50 and 80 Hz at four sound pressure levels, from about 6 dB to 24 dB above average hearing threshold, were selected as pure tones. The combined tones were combinations of two tones: the four levels of 31.5, 50 and 80 Hz tones and a constant level 40 Hz tone. The results showed that the rate of increase in annoyance of pure tones with increase in the sound pressure level was higher at lower frequencies, as reported in previous studies. The results for the combined tones showed that the increase in the annoyance of the combined tone compared to the annoyance of pure tone was dependent on the level difference of the two tones and their frequency separation. These results were compared with the evaluation obtained from different objective methods. The three methods were Moore's loudness model, the low frequency A-weighting and the total energy summation used as objective evaluation methods. Among the methods, the low frequency A-weighting gave the best correlation.

  This paper presents experimental measurements of masked thresholds of low frequency tones under background noises and application of loudness model to estimate the thresholds. The measurements of thresholds for tones at frequencies 20, 31.5, 40 and 50 Hz were conducted under three background noise conditions: one ambient noise and 60-100 Hz band-pass noises at two levels. The measurements were carried out in an uncontrolled environment in relatively quiet times. The perception thresholds of the same subjects were also measured for frequencies 31.5, 40 and 50 Hz inside a cabin with ambient noise levels well below the average hearing thresholds specified in ISO 389-7. Moore's loudness model has been used to estimate the masked thresholds. The estimated thresholds from the loudness model have been compared with the results obtained in the experiment. The results indicate that the noise above 50 Hz is effective in masking the low frequency tones at 50 Hz and below, and that Moore's loudness model can predict reasonably the average of the measured masked thresholds.

  Linear lumped parameter models of the apparent masses of human subjects in standing positions when exposed to vertical whole-body vibration have been developed. Simple models with a single degree-of-freedom (d.o.f.) and with two (d.o.f.) were considered for practical use. Model parameters were optimised using both the mean apparent mass of 12 male subjects and the apparent masses of individual subjects measured in a previous study. The calculated responses of two (d.o.f.) models with a massless support structure showed best agreement with the measured apparent mass and phase, with errors less than 0.1 in the normalised apparent mass (i.e., corresponding to errors less than 10% of the static mass) and errors less than 5degrees in the phase for a normal standing posture. The model parameters obtained with the mean measured apparent masses of the 12 subjects were similar to the means of the 12 sets of parameters obtained when fitting to the individual apparent masses. It was found that the effects of vibration magnitude and postural changes on the measured apparent mass could be represented by changes to the stiffness and damping in the two (d.o.f.) models.

  Perception thresholds of complex low frequency noises have been investigated in a laboratory experiment. Sound pressure levels that were just perceptible by subjects were measured for three complex noises and three pure tones. The complex noises had a flat constant spectrum, over the frequency range 2 to 10, 20, or 40 Hz and decreased at 15 dB per octave at higher frequencies. The frequencies of the pure tones used in this study were 10, 20 and 40 Hz. The perception thresholds were obtained using an all-pass filter, one-third octave band filters, and the G frequency weighting defined in ISO 7196. The G-weighted sound pressure levels obtained were compared with 100 dB which is described in ISO 7196 as the G-weighted level corresponding to the threshold of sounds in the frequency range 1 to 20 Hz. The perception thresholds of the pure tones measured in this study were comparable to the results available in various previous studies. The one-third octave sound pressure levels obtained for the thresholds of the complex noises appeared to be lower than the measured thresholds of the pure tones. The G-weighted sound pressure levels obtained for the thresholds of the complex noises appeared to be lower than 100 dB.

  This paper presents the identification and discussion of changes in modal parameters of atypical four-story reinforced concrete building undergone renovation. The aim of this study is to apply and evaluate the procedures of the well-established modal parameter identification technique using ambient vibration measurement. Correlation function is first used to transform ambient vibration response into impulse response and then modal parameters, i.e. frequencies, damping ratios, and mode shapes, are identified by Eigensystem Realization Algorithm (ERA). The study shows that the major difficulty in identification of modal parameter from ambient vibration can be attributed to low signal-to-noise ratio, especially in higher frequency range. It was found that reliable estimation of frequencies of the building could be obtained whereas larger variation can be observed in case of damping ratio. Changes in modal frequencies of the building can be clearly observed in agreement with the changes in structural configuration.

  The effect of the magnitude of vertical vibration on the dynamic response of the seated human body has been investigated. Eight male subjects were exposed to random vibration in the 0.5 to 20 Hz frequency range at five magnitudes: 0.125, 0.25, 0.5, 1.0 and 2.0 ms(-2) r.m.s. The dynamic responses of the body were measured at eight locations: at the first, fifth, and tenth thoracic vertebrae (T1, T5, T10), at the first, third, and fifth lumbar vertebrae (L1, L3, L5) and at the pelvis (the posterior-superior iliac spine). At each location, the motions on the body surface were measured in the three orthogonal axes within the sagittal plane (i.e., the vertical, fore-and-aft, and pitch axes). The force at the seat surface was also measured. Frequency response functions (i.e., transmissibilities and apparent mass) were used to represent the responses of the body. Non-linear characteristics were observed in the apparent mass and in the transmissibilities to most measurement locations. Resonance frequencies in the firequency response junctions decreased with increases in the vibration magnitude (e.g.for the vertical transmissibility to L3, a reduction from 6.25 to 4.75 Hz when the vibration magnitude increased from 0.125 to 2.0 ms(-2) r.m.s.). The transmission of vibration within the spine also showed some evidence of a non-linear characteristic. It can be concluded from this study that the dynamic responses of seated subjects are clearly non-linear with respect to vibration magnitude, whereas previous studies have reported inconsistent conclusions. More understanding of the dependence on vibration magnitude of both the dynamic responses of the soft tissues of the body and the muscle activity (voluntary and involuntary) is required to identify the causes of the non-linear characteristics observed in this study.

  Differences in vibration magnitude required for a human subject to differentiate whole-body vertical sinusoidal vibrations, difference thresholds for amplitude of sinusoidal vibration, have been determined at a vibration magnitude of 0.7 m/s(2) r.m.s. at five octave band center frequencies from 4 to 63 Hz and at 80 Hz. The median difference thresholds of 16 male subjects seated on a flat rigid seat were found between 0.037 and 0.046 m/s(2) r.m.s. at the frequencies used in this study. The subjects tended to be more sensitive to the change in vibration magnitude at 4 Hz than at 16, 31.5 and 63 Hz and less sensitive to the magnitude difference at 31.5 Hz than at 4, 8 and 80 Hz. The median relative difference thresholds, Weber's ratios, varied from 5.2% to 6.5% which were lower compared to the relative difference thresholds determined in the previous studies at frequencies where comparable data were available. The causes of the difference in the relative difference thresholds observed between this study and previous studies may include the difference in the psychophysical method used to determine the difference threshold.

• Effect of muscle tension on non-linearities in the apparent masses of seated subjects exposed to vertical whole-body vibration　　　　　　　　　　　　　　　
  Y Matsumoto; MJ Griffin
  JOURNAL OF SOUND AND VIBRATION, Volume：253, Number：1, First page：77, Last page：92, May 2002
  In subjects exposed to whole-body vibration, the cause of non-linear dynamic characteristics with changes in vibration magnitude is not understood. The effect of muscle tension on the non-linearity in apparent mass has been investigated in this study. Eight seated male subjects were exposed to random and sinusoidal vertical vibration at five magnitudes (0.35-1.4m/s(2) r.m.s.). The random vibration was presented for 60 s over the frequency range 2.0-20 Hz; the sinusoidal vibration was presented for 10 s at five frequencies (3.15, 4.0, 5.0, 6.3 and 8.0 Hz). Three sitting conditions were adopted such that, in two conditions, muscle tension in the buttocks and the abdomen was controlled. It was assumed that, in these two conditions, involuntary changes in muscle tension would be minimized. The force and acceleration at the seat surface were used to obtain apparent masses of subjects. With both sinusoidal and random vibration, there was statistical support for the hypothesis that non-linear characteristics were less clear when muscle tension in the buttocks and the abdomen was controlled. With increases in the magnitude of random vibration from 0.35 to 1.4m/s(2) r.m.s., the apparent mass resonance frequency decreased from 5.25 to 4.25 Hz with normal muscle tension, from 5.0 to 4.38 Hz with the buttocks muscles tensed, and from 5.13 to 4.5 Hz with the abdominal muscles tensed. Involuntary changes in muscle tension during whole-body vibration may be partly responsible for non-linear biodynamic responses. (C) 2002 Elsevier Science Ltd. All rights reserved.

• Effect of phase on human responses to vertical whole-body vibration and shock - Analytical investigation

  JOURNAL OF SOUND AND VIBRATION, Volume：250, Number：5, First page：813, Last page：834, Mar. 2002
  The effect of the "phase" on human responses to vertical whole-body vibration and shock has been investigated analytically using alternative methods of predicting subjective responses (using r.m.s., VDV and various frequency weightings). Two types of phase have been investigated: the effect of the relative phase between two frequency components in the input stimulus, and the phase response of the human body. Continuous vibrations and shocks, based on half-sine and one-and-a-half-sine accelerations, each of which had two frequency components, were used as input stimuli. For the continuous vibrations, an effect of relative phase was found for the vibration dose value (VDV) when the ratio between two frequency components was three: about 12% variation in the VDV of the unweighted acceleration was possible by changing the relative phase. The effect of the phase response of the body represented by frequency weightings was most significant when the frequencies of two sinusoidal components were about 3 and 9 Hz. With shocks, the effect of relative phase was observed for all stimuli used. The variation in the r.m.s. acceleration and in the VDV caused by variations in the relative phase varied between 3 and 100%, depending on the nature of stimulus and the frequency weighting. The phase of the frequency weightings had a different effect on the r.m.s. and the VDV. (C) 2002 Elsevier Science Ltd.

  An experimental study has investigated the effect of "phase" on the subjective responses of human subjects exposed to vertical whole-body vibration and shock. The stimuli were formed from two frequency components: 3 and 9 Hz for continuous vibration,, and 3 and 12 Hz for shocks, The two frequency components, each having 1.0 ms(-2) peak acceleration, were combined to form various waveforms. The effects of the vibration magnitude on the discomfort caused by the input stimuli were also investigated with both the continuous vibrations and the shocks. Various objective measurements of acceleration and force at the seat surface, the effects of different frequency weightings and second and fourth power evaluations were compared with judgments of the discomfort of the stimuli. It was found that a 6% to 12% increase in magnitude produced a statistically significant increase in discomfort with both the continuous vibrations and the shocks. Judgements of discomfort caused by changes in vibration magnitude were highly correlated with all of the objective measurements used in the study. The effects on discomfort of the phase between components in the continuous vibrations were not statistically significant, as predicted using evaluation methods with a power of 2. However, small changes in discomfort were correlated with the vibration dose value (VDV) of the W-b frequency-weighted acceleration. The effect of phase between frequency components within the shocks was statistically significant, although no objective measurement method used in the study was correlated with the subjective judgments.

  An energy-based method of damping evaluation is adopted for investigating the damping characteristics of bridges. The method is based on the energy representation of modal damping ratio in which the energy dissipated in a mode is evaluated by summing up all possible damping sources. As a result, the modal damping ratio is semi-analytically evaluated by using the bridge modal characteristics with some of damping parameters. The modal damping ratios evaluated for different modes in various types of bridges are then compared I with the experimentally field-measured data in order to discuss the damping characteristics of bridges as well as the applicability of energy-based evaluation method.

• Modelling the dynamic mechanisms associated with the principal resonance of the seated human body　　　　　　　　　　　　　　　
  Y Matsumoto; MJ Griffin
  CLINICAL BIOMECHANICS, Volume：16, Number：Sup.1, First page：S31, Last page：S44, 2001
  Objective. Simple mathematical models have been developed to obtain insights into resonance phenomena observed at about 5 Hz in the dynamic responses of the seated human body exposed to vertical whole-body vibration.
  Design. Alternative lumped parameter models with a few degrees-of-freedom have been investigated. Rotational degrees-of-freedom, with eccentricity of the centre of gravity of the mass elements, represented responses in the fore-and-aft and pitch axes caused by vertical vibration.
  Background. The causes of body resonance are not fully understood, but this information is required to develop cause-effect relationships between vibration exposures and effects on human health, comfort and performance.
  Method. The inertial and geometric parameters for models were based on published anatomical data. Other mechanical parameters were determined by comparing model responses to experimental data.
  Results. Two models, with four and five degrees-of-freedom, gave more reasonable representations than other models. Mechanical parameters obtained with median and individual experimental data were consistent for vertical degrees-of-freedom but varied for rotational degrees-of-freedom.
  Conclusions. The resonance of the apparent mass at about 5 Hz may be attributed to a vibration mode consisting of vertical motion of the pelvis and legs and a pitch motion of the pelvis, both of which cause vertical motion of the upper-body above the pelvis, a bending motion of the spine, and vertical motion of the viscera.

• Comparison of biodynamic responses in standing and seated human bodies　　　　　　　　　　　　　　　
  Y Matsumoto; MJ Griffin
  JOURNAL OF SOUND AND VIBRATION, Volume：238, Number：4, First page：691, Last page：704, Dec. 2000
  The dynamic responses of the human body in a standing position and in a sitting position have been compared. The apparent mass and transmissibilities to the head, six locations along the spine, and the pelvis were measured with eight male subjects exposed to vertical whole-body vibration. In both postures, the principal resonance in the apparent mass occurred in the range 5-6 Hz, with slightly higher frequencies and lower apparent mass in the standing posture. There was greater transmission of vertical vibration to the pelvis and the lower spine and greater relative motion within the lower spine in the standing posture than in the sitting posture at the principal resonance and at higher frequencies. Transmissibilities from the supporting surface (floor or seat) to the thoracic region had similar magnitudes for both standing and sitting subjects. The lumbar spine has less lordosis and may be more compressed and less flexible in the sitting posture than in the standing posture. This may have reduced the relative motions between lumbar vertebrae and both the supporting vibrating surface and the other vertebrae in the sitting posture. The characteristics of the vibration transmitted to the pelvis may have differed in the two postures due to different transmission paths. Increased forward rotation of the pelvis in the standing posture may have caused the differences in responses of the pelvis and the lower spine that were observed between the two postures.

• Movement of the upper-body of seated subjects exposed to vertical whole-body vibration at the principal resonance frequency

  JOURNAL OF SOUND AND VIBRATION, Volume：215, Number：4, First page：743, Last page：762, Aug. 1998
  The dynamic responses of eight male subjects exposed to vertical whole-body vibration have been measured at eight locations of the body in three directions within the sagittal plane: in the vertical, fore-and-aft and pitch axes. The motions were measured on the body surface at the first, fifth and tenth thoracic vertebra (T1, T5, T10), at the first, third and fifth lumbar vertebra (L1, L3, L5) and at the pelvis (the posterior-superior iliac spine), and were corrected so as to estimate the motions of the skeleton. The head motion was measured with a bite-bar. The force at the seat surface was also measured. The subjects were exposed to vertical random vibration in the frequency range from 0.5-20 Hz at a magnitude of 1.0 ms(-2) r.m.s. The movement of the upper-body at the principal resonance frequency of the driving-point apparent mass is illustrated by using the transmissibilities from seat vertical vibration to vertical and fore-and-aft vibration at the eight locations on the body. A bending of the lumbar spine, and probably the lowest thoracic spine, possibly coupled with a rocking motion of the upper thoracic spine about the lower thoracic spine, appeared to be dominant. A small bending along the full length of thoracic spine was also found. Pitch motion of the pelvis, possibly accompanied by longitudinal and shear deformations of the tissue underneath the pelvis, was found to occur near the resonance frequency range, but did not appear to make a principal contribution to the resonance observed in the apparent mass. Any significant axial motions along the spine occurred at higher frequencies. (C) 1998 Academic Press.

• Dynamic response of the standing human body exposed to vertical vibration: Influence of posture and vibration magnitude　　　　　　　　　　　　　　　
  Y Matsumoto; MJ Griffin
  JOURNAL OF SOUND AND VIBRATION, Volume：212, Number：1, First page：85, Last page：107, Apr. 1998
  The influence of the posture of the legs and the vibration magnitude on the dynamic response of the standing human body exposed to vertical whole-body vibration has been investigated. Motions were measured on the body surface at the first and eighth thoracic and fourth lumbar vertebrae (TI, T8 and L4), at the right and left iliac crests and at the knee. Twelve subjects took part in the experiment with three leg postures (normal, legs bent and one leg), and five magnitudes of random vibration (0.125-2.0 ms(-2) r.m.s.) in the frequency range from 0.5-30 Hz. The main resonance frequencies of the apparent masses at 1.0 ms(-2) r.m.s. differed between postures: 5.5 Hz in the normal posture, 2.75 Hz in the legs bent posture and 3.75 Hz in the one leg posture. In the normal posture, the transmissibilities to L4 and the iliac crests showed a similar trend to the apparent mass at low frequencies. With the legs straight, no resonance was observed in the legs at frequencies below 15 Hz. In the legs bent posture, a bending motion of the legs at the knee and a pitching or bending motion of the upper-body appeared to contribute to the resonance of the whole body as observed in the apparent mass, with attenuation of vibration transmission to the upper body at high frequencies. In the one leg posture, coupled rotational motion of the whole upper-body about the hip joint may have contributed to the resonance observed in the apparent mass at low frequencies and the attenuation of vertical vibration transmission at high frequencies. The resonance frequency of the apparent mass in the normal posture decreased from 6.75-5.25 Hz with increasing vibration magnitude from 0.125 to 2.0 ms(-2) r.m.s. This "softening" effect was also found in the transmissibilities to many parts of the body that showed resonances. (C) 1998 Academic Press Limited.

  The field measurement of noise and vibration in a PC box-girder bridge with the modular type expansion joint was conducted in order to investigate the characteristics and mechanism of the noise generated from the modular joint possible sound radiating vibration modes of this structure under a vehicle passage. Three components of noise from modular joint are discussed by paying attention to non-stationary phenomenon of the noise generation and propagation. Effects of bridge type, car type and car running speed are also studied on thenoise characteristics.

  Volume：38, First page：143, Last page：144, Mar. 2005
  An experiment has been conducted to investigate the characteristics of human perception of complex low frequency noise. Fifteen subjects took part in the experiment in which the perception thresholds of complex tones consisting of two frequency components and pure tones were measured. The frequencies of the tones used in the experiment were 25, 31.5, 40 and 50 Hz. For the complex tones, the perception thresholds were determined by changing the sound pressure level of a frequency component while the sound pressure level of another frequency component was fixed at 5 or 10 dB below the pure tone perception threshold at the corresponding frequency. It was found that the frequency component at the level below the pure tone thresholds might have an effect on the perception of the complex tone.

  The objective of this research was to propose a reasonable evaluation method for environmental vibration caused by vibration of bridges based on human subjective responses to vibration. Such vibration can have the following characteristics: dominant horizontal vibration which has a transient nature depending on traffic condition, horizontal vibration combined with vertical vibration, and vibration combined with audible noise correlated with the vibration. Subjective responses to vibrations with those characteristics were investigated in laboratory experiments and the experimental data that can be applicable to the development of evaluation methods were able to be accumulated.

  The purpose of this study is to quantitatively examine the combineeffects of noise and vibration due to railways on the living environment, and to obtain knowledge on the effects that will occur in the living environment along railway lines and specific measures to be implemented. From the experimental results, it was confirmed that not only the loudness of the sound but also the loudness of the vibration affects the reading disturbance. It was also shown that the effect of vibration on annoyance was small when the noise stimulus was large, and the effect of vibration was particularly large when the noise stimulus was small. In the comparison between horizontal and vertical vibrations, there was no difference in loudness, annoyance, and disturbance with respect to vibration when passing through a railway, and with regard to the degree of concern, even with the same vibration level, with respect to horizontal vibration rather than vertical vibration.

  This survey was conducted in November 2016, one year after the opening of the Hokuriku Shinkansen Line. Questionnaires were distributed to the inhabitants of 20s and the older living in detached houses along the railway in Ishikawa and Toyama prefectures by mailing method. We selected 1,980 households for survey cooperation and got 1,0022 responses. The main question items were as follows: housing and living environments, transportation facilities (including noise and vibration), lifestyle habits and individual factors. We examined the relationship between noise and community responses. Annoyance caused by respondents in area without conventional railway was significant higher than that in other area. Evaluation of falling asleep disturbance and dissatisfaction of opening window were also influenced by existence of conventional railway in residential area.
  We are planning to investigate the combined effects of noise and vibration in the future.

  In this study, it fundamental investigation aimed at enabling a reduction in the construction work vibration using a vibrating system or mass. The effects of the equipment were verified by model experiments and analysis by three-dimensional ground model. It was confirmed that the vibration system obtained effects from a low vibration frequency. It was confirmed that the mass body obtained the effect with higher frequency than the vibration system. In any case, it was confirmed that the reduction effect was maximized on the back side of the device. These devices are smaller than conventional countermeasure techniques. Therefore, it is effective for pinpoint measures, such as when houses get close to construction boundaries.

  The temperature dependence of mechanical characteristics of high damping rubber bearings (HDRBs) was investigated through cyclic loading tests under different ambient temperatures, especially sub-zero environment. The ambient temperatures and temperatures inside HDRBs during cyclic loading were
  different due to self hating, and it is found that mechanical behavior of HDRBs is governed by the inside temperatures. A simple method to estimate the inside temperature was developed on the basis of the cyclic loading tests and thermal conductivity analyses results. Previous cyclic loading tests results at different ambient temperatures were reexamined based on the inside temperatures to estimate temperature dependence of HDRBs.

  A purpose of the studies is to establish a design technology about the TMD (Tuned Mass Damper) control to take measures by ground environment vibration to occur by a construction machine.
  The reduction effect of the environmental ground vibration by the TMD control was inspected by the vibration response analysis using the three-dimensional ground model and the experiment using the size of the original model. It was revealed that the vibration reduction effect of the TMD control greatly depended on the mass of TMD system, damping of TMD system, and the ratio of frequency for control and the resonance frequency of TMD system. The vibration reduction effect by the TMD control grows big so that the TMD mass is big, the damping is low, and the frequency ratio is almost 1. We will examine the power of the construction machine and the relations with the TMD control parameter.

  Damages (such as tension crack, corrosion and partial fracture) and damage –induced local damping increment in steel member, concrete member and steel-concrete interface are first experimentally studied to discuss the mechanism of local damping increased by local damages. The evaluation method of structural health condition for steel, RC and PC bridges is then proposed by developing a hybrid method of experimental and analytical modal syntheses based on ambient vibration measurement and global damping change monitoring. The method of ambient vibration measurement is carefully studied for optimizing it as a system and the identification of global damping change in bridges is refined with FE model updating method. How to implement the proposed method of bridge health evaluation to the Bridge Management System was finally discussed.

  The objective of this research is to investigate the mechanism, annoyance and control of environmental noises generated by vehicle passage through modular type expansion joint in highway bridges. The research results are summarized as follows.1. The mechanism and control of noise generation for modular expansion joints were investigated in experiments on a full-scale model of the joint. Noise and vibration of the joint model were measured when a car was running over the model. It was concluded, based on this measurement together with tests of the acoustic and dynamic characteristics of the joint model, that the noise from the top of the joint could be attributed to a sudden change in the air pressure in the gaps formed by the sealing rubber elements, and the noise from the bottom was probably caused by sound radiation from vibration of the middle beams. Effects of some proposed noise control measures were also investigated experimentally.2. Field measurements of noise and vibration were conducted in a non-composite I-shaped steel-girder bridge and in a PC box girder bridge with modular expansion joints. In each case, the noise was measured at several points above and below the bridge when different type of vehicles passed over the joint with different speeds. The non-stationary characteristics of noise propagation in the field and effects of bridge, vehicle, and joint types were clarified. Possible sources of environmental noise problem were also discussed by studying the A-filtered spectra of sound pressures and their non-stationary characteristics.3. The annoyance of field-measured noises of modular type joint was also investigated by psychoacoustic experiment in a laboratory in order to identify the annoying noise components.

  The main objective of this study is to develop an energy-based method for evaluating damping characteristics of structures with special reference to sub-structural interaction. The main parts of the present study are summarized as follows.
  1. The coupled cable-vibration characteristics and its effect on the modal damping characteristics have been investigated for long-span cable-stayed bridges by conducting the experimental modal analysis based on ERA, the theoretical modal analysis based on FEM, and the damping analysis based on sub-structural synthesis for the Tatara Bridge.
  2. A explicit formula for modal damping of girder bridge has been derived by applying the energy-based evaluation method with an assumption of girder's internal damping and support's friction damping, and its validity has been checked with field vibration data as well as a model experiment data. The damping mechanism of girder bridges has been also clarified by evaluatin damping contributions of substructures such as concrete slab and steel main girder in 2-girders and 4-girders bridges.
  3. The energy-based damping analysis of a cable system model consisting of two identical cables with a secondary cable was conducted and the results were compared with the experimental ones. It is concluded that the modal damping of system can be made higher by means of internal resonance among substructures.
  4. Robust performance of hysteretic dampers, used in controlling mid-rise buildings, against change of earthquake characteristics is investigated by introducing an energy-based damper performance index. It is found out that, besides the effect of maximum energy input on damper efficiency, othertime dependant properties as energy-based effective duration and earthquake dominant period have great influence on the damper efficiency.
  5. A general method for evaluating a damping matrix of structure has been studied by considering an equivalent complex stiffness matrix but is still under investigation.

  The microstructure and the mechanical behavior of natural rubber (NR) and high damping rubber (HDR) were investigated. In this study, most of the attention was paid to the compression regime. The mechanical tests revealed the existence of Mullins' effect, strainrate dependency, hystersis and residual strain effects in all the specimens. In NR, the extent of these effects were found to have a inherent relation with the presence of microstructural voids. The presence of all these effects was also found to be significant in HDR. In addition, the strain-rate dependent high initial stiffness feature at low compressive stretch levels also became evident from the experiments. However, the microstructural observation of the current study could not explain these features of HDR. This prompted for the need of considering a phenomenological approach to reach a general constitutive model.
  A constitutive model based on phenomenological motivation was introduced to model the strain-rate dependency. An improved hyperelasticity model was proposed to represent the rate-independent elastic responses including high initial stiffness characteristics. A comparative evaluation was carried out to display the better performance of the proposed hyperelasticity model over the conventional ones. The hyperelasticity relation was incorporated in a finite deformation rate-dependent model structure. A parameter identification scheme was proposed to identify the parameters for the equilibrium and the instantaneous responses from the experimental data. The difficulties of direct application of infinitely fast or slow loading rate on such highly viscous material to obtain these responses and thereby to identify the nonlinear elastic parameters were overcome. Experimental results were extrapolated and the proposed hyperelasticity model was used. The proposed scheme was applied on three types of specimens. Numerical simulation of the test results at different deformation modes followed by sensitivity studies verified the adequacy and the robustness of the proposed model and the parameter identification scheme.
