BRIDGE VIBRATION STUDIES

The objective of this investigation was to study the vibration of highway bridges due to moving vehicles and the effect of vibrations on bridge users. In order to establish a criterion for human response to vibration, the available literature on human response to vibration was reviewed. As a result of this study it was found that for the low range of frequencies, maximum jerk and for the medium range of frequencies, maximum acceleration are the main causes of the disturbance to the human body. Maximum values of jerk and acceleration for user comfort were suggested. An extensive parametric study was done on jerk and acceleration, which showed that surface roughness had the most effect and that girder flexibility had very little effect. As a result of the comparison between the analytical results and the field results, it was concluded that the dynamic response of a bridge to a vehicle could be determined, with a reasonable degree of accuracy, by using the analytical programs. A simplified method was also suggested that could be used to determine the maximum dynamic responses, such as acceleration and jerk, of a bridge due to a given vehicle. /Author/
