摘　　要：通过考虑铅芯橡胶支座和桥梁结构的非线性特性及相互影响 ,建立了全桥模型 ,并通过改变铅芯橡胶支座动力参数、桥梁结构的自振周期和输入地震激励等 ,进行连续梁桥地震响应时程分析 。In this paper, the characteristics of seismic response of continuous beam bridges equipped with lead rubber bearings are investigated by nonlinear time history analysis. The dynamic parameters of lead rubber bearings and the inherent period of bridge structure are changed as well as the seismic input. The nonlinear properties and interactive effect of lead rubber bearing and bridge structure are also considered.
