摘　　要：基于等效线性化法对并联复合隔震体系进行了简化计算分析。首先通过推导,将由基底剪力和位移表达的恢复力模型转化为基底剪力系数和位移模型;然后依据最新的建筑抗震设计规范,对简化分析方法的应用进行阐释;最后结合基底剪力系数和位移的结果,对并联复合隔震体系的隔震性能进行了分析,重点考察了不同刚度系数、摩擦承压比、场地特征周期的影响。结果表明:简化分析方法可以便捷有效地用于并联复合隔震体系的初步设计,为并联复合隔震体系的推广和应用奠定了基础。The simplified analysis of the parallel composite isolation system was carried out based on equivalent linearization method. First of all,through the derivation,the restoring force model expressed in the form of basal shear force and displacement was converted to the basal shear force coefficient and displacement model; then,according to the new code for seismic design of buildings,the application of the simplified analysis method was explained. Finally,combined with the results of the basal shear coefficient and the displacement,the seismic isolation performance of the parallel composite isolation system was analyzed,focusing on the effects of different stiffness coefficients,friction bearing ratios and site characteristic periods. The results showed that the simplified analysis method could be conveniently and effectively used for preliminary design of the parallel composite isolation system,which laid a foundation for the popularization and application of the parallel composite isolation system.
