摘要

由于底部可利用的大空间及隔震层设置的便利性,大底盘隔震的塔楼结构的应用范围越来越广,相关的研究也越来越多.但塔间距变化对该类结构隔震设计影响的研究还较少,本文以某大底盘隔震的双塔楼结构为例,详细深入研究了这个问题,对不同塔间距的双塔楼的隔震效果进行综合的对比分析,为该类双塔楼的设计提出可供参考的依据.
Because of the attractive open space underneath the building and the convenience of isolation layer of setting,the application of large base structure with double tower is more and more widely,the relevant studies also more and more.But the impact study about tower spacing for this type of structure to the isolation affects also less,thus,in this paper the authors conducted the research.This paper uses a large-scale finite element software-ETABS to do the numerical simulation analysis,with large base structure with twin towers as an example,through adjusting the tower spacing of structure,comparison and analysis the seismic isolating coefficient,the horizontal earthquake effect coefficient and the period ratio of modes of the structure with different spacing,then draws the relationship between tower distance and vibration isolation of the large base structure with twin towers,to provide reference for the design of this kind of buildings.
