某多层房屋RC框架和支撑-钢框架抗震性能分析

Seismic Performance of RC Frame Structure and Stell Structure With Bracing of a Building

采用结构设计软件SATWE 2010计算某建筑采用RC框架体系和支撑-钢框架结构的抗震性能,对两种结构体系在多遇地震下的参数进行比较分析。结果表明:支撑-钢框架体系侧移刚度要大过RC框架体系,位移限值较小;合理布置支撑的钢框架体系能有效抑制结构的扭转效应;支撑-钢框架体系的整体稳定性和RC框架体系相当。

Using the structure design software SATWE 2010 to calculate a building by the seismic performance of RC frame system and a steel braced frame structure, the two kind of structure system in frequently occurred earthquake parameters are compared and analyZed. The results showed that： braced steel frame system side shift stiffness is greater than RC frame system, the displacement limit value is small; rational arrangement of supports of the steel frame system can effectively inhibit the structure torsion effect;support-steel frame system of the overall stability and reinforced concrete （RC） system is.
