Seismic response of long-span cable stayed bridge under asynchronous excitations

Seismic response of long-span cable-stayed bridge had been studied by establishing a dynamic model of cable-stayed bridge through FEA software ANSYS10.0,and by analyzing the response with the dynamic time-history.In the seismic response analysis of the influences of wave-passage effect on long-span cable-stayed bridge with twin towers under non-uniform excitation are discussed.A conclusion is given that the uniform seismic excitation is not able to control the seismic design for the long-span cable-stayed bridge.In order to get accurate results,the influences of local site effect and wave-passage effect on seismic response should be considered.
