摘　　要：在高层隔震结构设计中,为能较准确地选择隔震支座,尝试将地震作用减少至1/3～1/2输入原高层抗震结构中,将计算所得结构底部竖向反力作为隔震支座选择的依据.为方便设计人员掌握,将基于Etabs有限元软件,以《建筑抗震设计规范》中的12章及相关规程为参考,以一实例讲述高层隔震结构的设计流程.结果表明,此设计方法便捷有效.To choose the right bearings accurately in the design of high-rise isolated structure,the method that the seismic action will be reduced to 1/3~1/2 input to high-rise seismic structure and the calculation results of vertical support reaction at the bottom of the structure will be considered as the basis of choosing bearings.To make designers easily master this method,the design process proposed by this paper will be represented by taking a pratical project for example,which is based on Etabs finite elements software and according to the 12 th chapter of 《Code for seismic design of buildings》 and some other relevant standards,and the results show that this method is convenient and effective.
