Abstract
Complaints due to traffic vibration of highway bridges have a strong correlation between the vertical vibration of the superstructure of the bridge. Therefore, to determine countermeasure methods, a vehicle load analysis which considers dynamic interaction when the vehicle travels on the bridge, is used. However, this analysis method requires specialized skill and knowledge. In this study, the authors have proposed an analysis method that can be applied using a general-purpose software, by determining an external force of the frequency band which is causing complaints, using the actual measured value of the vehicle vibration. The vibration of the typical plate girder bridges with/without countermeasures has been estimated by the proposed analysis method. It was confirmed that the proposed analysis method simulates roughly and simply the bridge vibration and is feasible for practical use.
