摘　　要：运用ETABS建立隔震结构的有限元模型,对铅芯隔震橡胶支座屈服前刚度不同取值的隔震结构进行了时程分析,通过对比分析,给出了隔震设计中的铅芯隔震橡胶支座屈服前刚度取值的合理建议.The authors use ETABS program to build through time-history analysis of the structure which uses shear stiffness, and give reasonable advice to setting initial seismic-isolation design. te element model of the seismic-isolation structure, the lead rubber bearing setting with different initial shear stiffness of the lead rubber bearing used in the

关 键 词：ETABS 隔震结构 屈服前刚度
