托柱转换结构的弹性抗震性能研究

Study on the elastic seismic performance of the supporting column transfer structure

采用SAP2000软件,以托柱转换结构为算例,进行空腹桁架转换结构与梁式转换结构的基本动力特性和弹性动力时程响应对比研究。结果表明,两种托柱转换结构的基本动力特性和弹性动力时程响应非常接近,说明弹性抗震性能相近,采用空腹桁架作为转换构件的方案在抗震方面是完全可行的。

By means of SAP2000 software,we compare the difference of both the basic dynamic properties and elastic dynamic time-history response between the vierendeel truss type transfer structure and the beam type transfer structure with supporting column transfer structure as calculating example.The results show that the two transfer structure have the similar dynamic properties and elastic dynamic time-history response,which means that the elastic seismic performance is similar.So that,the scheme that vierendeel truss is used as transfer structure for anti-seism is feasible.
