基础隔震技术的应用及其经济性分析

Application and economic analysis about base isolation technology

以某框架结构为例,对其采用不同隔震支座进行基础隔震设计,对采用不同的隔震支座的隔震结构和抗震结构采用大型有限元分析软件SAP2000进行地震作用下的动力时程分析,同时,还对采用铅芯叠层橡胶支座方案进行了经济性分析.分析结果表明,该框架结构在应用铅芯橡胶隔震支座时隔震设计效果明显,采用铅芯橡胶支座结构具有明显的社会效益和经济效益.

A frame structure is taken as an example in this paper and different isolation bearings are adopted for the design of base isolation, making a dynamic time-history analysis by using of large-scale structural finite element analysis software SAP2000 about base-isolated structure and anti-seismic structure using the different isolation bearings. Then,an economic analysis about the project using lead-core rubber bearings is done. The results showed that it has an obvious effect on the isolation design when the lead-core rubber bearings are used on this frame structure, and it has significant social and economic benefits.
