某多层框架结构基础隔震设计研究

Research on base isolation design of a multi-storied frame structure

借助SAP2000有限元分析软件,以某一实际多层框架工程结构为研究对象,利用减隔震技术,对该结构进行了橡胶支座隔震设计,使之抗震安全性得到了提高,且满足建筑结构抗震设计规范的要求,研究结果可为今后类似的工程结构基础隔震设计提供参考。

With finite element analysis program SAP2000,selecting a practical multilayer framework structure as the research object,seismic reduction and isolation technology was using in the structure design with rubber bearing isolation. The result shows that,after rubber bearing isolation design,the structural seismic safety has been improved,and the maximum floor response are meet the requirements of the building seismic design code. This study can provide a useful reference for future similar structural rubber bearing isolation design.
