| Abstract: | In this paper, a 3-D finite element model is made by general software ANSYS on the background of Dongtinghu big bridge in Yueyang. The lead-rubber bearings are proposed to be used as the seismicity mitigation devices at the connections between the deck and pylons of cable-stayed bridge. The different seismic response of the bridge is computed with different frequency seismic waves. The results show that the LRB has an entirely different effect to the seismic response of cable-stayed bridge under different frequency seismic waves. |
