Abstract
Due to the great weight of the large continuous girder,seismic problem is outstanding and the seismic isolation technology is one of the effective ways to solve the problem.Based on the(50+8×100+50)m prestressed concrete continuous girder,the seismic isolation technology of viscous damper with double spherical seismic bearing is applied.A finite element model is established to simulate the double spherical seismic bearing with bilinear model,and nonlinear time history response analysis are conducted by inputting three seismic motions with 50-year 2％exceedance probability.The results indicate that the seismic isolation measure allows all piers to share the seismic response and improve the seismic performance of bridge.As a result,all piers and pile foundations remain in elastic state and the maximum displacement of the bearing is controllable..关键词
