| Abstract: | Effects of isolation bearings on the seismic response of bridges are studied. The nonlinear dynamic response of bridges equipped with isolation bearings are analyzed by the FEM method. In the analysis, the nonlinear properties of bridges and isolation bearings are considered. The results of analysis show that bridges isolated with lead rubber bearings (LRB) perform better than those isolated with normal rubber bearings (RB) in an earthquake. The impacts of LRB parameters on the seismic response of bridges are studied. |
