Abstract

The heights and height differences of pier structures in different terrains vary, and their damage characteristics under seismic conditions also differ. In order to further explore the influence of pier height on the seismic resistance of rigid frame bridges, this study takes a group of equally high rigid frame bridges with different pier heights and a group of unequally high rigid frame bridges with different pier height differences as the research objects. The piers are taken as the main vulnerable components, and their seismic fragility is calculated and compared through Incremental Dynamic Analysis (IDA) method. The results show that the higher the piers of equally high rigid frame bridges, the smaller the probability of damage under seismic action; when the pier height is increased from 70 meters to 80 meters, the seismic performance of the piers is significantly improved compared to other pier heights.
