Nonlinear Seismic Response Analysis of Isolation Bridges

WANG Li,YAN Gui ping, FANG You liang (College of Civil Engineering and Architecture, Northern Jiaotong University, Beijing 100044,China)  
In this paper, according to the behavior of seismic isolation systems for bridges, the nonlinear behavior of aseismic bearings and ductile plastic hinges of piers are taken into account by using nonlinear spring element. One design example of a bridge is presented to investigate the effect of aseismic design. When nonlinear seismic response analysis is carried out, the isolation effect is discussed.
