| Abstract: | In the paper,a long-span cable-stayed bridge is taken as an example.The dynamic model of cable-stayed bridge included main bridge and approach bridges.Using response spectrum and time history analysis method to analysis the response under earthquake attacked.The study results indicate that the seismic performance of the cable-stayed bridge can meet the expected goal.The seismic response in longitudinal direction decreased obviously when allocated viscous dampers. |
