Seismic Damage Analysis on Double-Column Pier of Passenger Dedicated Line

Abstract:

Reasonable strong seismic motion records are selected according to the applicable Code of Seismic Design for Railway Engineering. By using FEA software, the FEA model of one double-column pier of passenger dedicated line is established with considering the effect of flexible base effects and seismic characteristic. Based on Park-Ang seismic damage model and nonlinear seismic response analysis, the seismic damage analysis on double-column pier of passenger dedicated Line is carried out. The study results are obtained as follow: 1) The seismic damage of bridge mainly happen during the early and middle stage of seismic motion. 2) There are still major discrepancies in the seismic damage made from the seismic records which come from the same site condition and have the same PGA. 3) Although PGA has a great effect on the seismic damage index, it has nothing to do with the happening time of max seismic damage index.
