| Abstract: | The paper studied the earthquake response of the Yong-an Bridge in Fushun City a concrete cable-stayed bridge with three towers and single cable plane with modal analysis of the bridge with ANSYS and the dynamic performances were obtained. The standard seismic response spectrum was used as input taking into account of longitudinal, transverse and vertical direction responses respectively. The seismic resistant capacity of this bridge was analyzed.It is indicated that the seismic resistant capacity of this bridge is ensured. |
