摘　　要：对橡胶垫减震结构中隔震层恢复力曲线进行了详细的研究，对该结构在弹塑性范围内进行了地震反应的动力分析，计算了结构在地震波作用下各层的位移反应，研究了橡胶垫水平刚度变化对动力分析的影响。并分析了不同的场地对建筑物减震效果的影响。这些都为结构设计提供了参考依据。A detailed study for the restore_force curve of isolation layer of isolation structure using rubber bearing is carried out.The dynamic analysis of earthquake response is described in elastic_plastic range. The displacement of each floor under earthquake wave is calculated. The influence from change of the rubber level stiffness in dynamic analysis is considered.Besides,the influence of isolating effect under the different place soil is analysed. These can provide the reference basis for construction design.
