| 摘 要： | 对某多层框架隔震结构采用三维有限元模型进行了非线性时程分析，分析了该结构在地震作用下的动力特性和地震反应性能。分析结果表明，多层框架隔震结构的地震反应低于相应抗震结构的地震反应，在隔震结构设计中采用有限元法能更全面地，准确地反映隔震结构的地震反应性能。

| Abstract: | A nonlinear time history analysis of a base isolated multistory frame structure modelled as the three dimensional finite element model is investigated.The dynamic characteristics and the seismic responses of the structure during an earthquake are studied.The results show that the seismic responses of the multistory frame structure are remarkably less than those of the relevant conventional multistory frame structure and that the finite element method can reflect comprehensively and correctly the seismic characteristics of the base isolated building in design. |
