摘要
利用大型结构有限元分析软件SAP2000对采用基础隔震框架结构在不同地震波作用下进行了动力时程分析,分析了基础隔震结构在地震作用下的位移、剪力,并与未隔震相同结构建筑的位移、剪力进行了对比,以评断隔震结构的减震效果,得到一些有意义的结论.结果表明,隔震结构在罕遇地震作用下仍处于弹性工作状态,具有优越的抗震性能.
The large-scale structural finite element analysis software SAP2000 is employed to make a dynamic time-history analysis of the base isolation frame interval on different waves.The earthquake responses of the isolated structure,including the displacement and shear force of each floor,are calculated and compared with those of the same structure without isolation.Then a comparative study of the calculation was conducted.Some useful results and conclusions are given.Research results indicate that the isolated structure has excellent anti-seismic behavior and remains in elastic state under the seldom-occurred earthquake.
