Seismic Response Analyses of Isolated Bridges with Different Isolation Bearings

Abstract:

In order to research the different types of isolation bearings impact on bridge performance, parameters of lead rubber bearing, super high damping rubber bearing and friction pendulum bearing are designed for the three-span continuous bridge. With the method of nonlinear time-history analysis, dynamic characteristic of this isolated bridge is studied by using sap2000. Analysis results show that the isolated bridge with three types isolation bearings has a good seismic isolation effect under rare earthquake. The difference of shear force between friction pendulum and other two types is about 4% below.
