摘　　要：新的建筑抗震设计规范将隔震结构列入其中,探讨分析了结构基础隔震应用中应注意的问题,提出了非线性动力时程分析计算模型并编制了程序。借助该程序,分析了基础隔震结构在地震作用下的层间位移、加速度和剪力等地震反应并与未隔震相同结构建筑的地震反应进行了对比。Isolators is included in the new earthquake-resistant standard. In this article some questions on base-isolators are analysed, and a non-linear dynamic analysis model is presented for it. A corresponding computer program is also compiled. With the program, the earthquake responses of a isolated structure induding the displacement, acceleration and shear force of each floor are calculated and compared with those of the same structure without base-isolation.
