摘要
利用有限元分析软件SAP2000构建6层纯框架轻钢结构,以此为基础对结构布置中心支撑(CBF)、偏心支撑(EBF)和钢板剪力墙(SPSW),计算在8度罕遇地震作用下的地震响应,从抗侧力、模态分析和动力时程分析,对4种结构体系进行弹塑性时程的对比分析,比较其动力特性及抗震性能。
The finite element analysis software SAP2000 was applied to establish a slx-store framework light steel structure. Base on the circumstance,the central support （CBF） ,the eccentric support （EBF） ,the corner support and the steel plate shear wall （SPSW） were individually made for the steel frame. The earthquake response was calculated under the rare earthquake of 8 degrees. The dynamic characteristics and the seismic resistance ability were compared, on the comparison of the elastic and plastic time history of four structure systems. From the lateral resistant ability and natural vibration period of the structure,the modal analysis and the dynamic analysis.
