Seismic response analysis of base-isolated bridge subjected to long duration earthquake in lowtemperature environment

抄録

This study introduces a dynamic bearing property definition method to evaluate the seismic performance of a base isolated bridge under severe cold environment. Low temperature effect of base isolation devices due to their material characteristics is particularly considered. Thermal production which results in temperature variation is also taken into account to ensure the accuracy and practicality of analysis results. For this purpose, the overall three-dimensional non-linear bridge dynamic response is examined in detail under long duration earthquake ground motions.
