摘要
为研究不同形式支撑对多层轻钢结构抗震性能的影响,文章通过运用非线性有限元分析软件SAP2000构建6层纯框架轻钢结构,以此为基础对结构分别布置中心支撑、偏心支撑和隅撑支撑,计算8度罕遇地震作用下结构的抗侧刚度、自振周期,并采用两条经典地震波对四种结构体系进行弹塑性时程的对比分析,比较四种钢框架结构的动力特性及抗震性能。
In order to study the different type support affected to anti earthquake performances of the multi light steel structure,a nonlinear finite element analysis software SAP2000 was applied to establish a six layers framework light steel structure.Base on the circumstance,the central support,eccentric support and corner support were individually made for the steel structure.The lateral rigidity and natural vibration period of the structure under an unusual 8 grade earthquake role was calculated.Two classic seismic waves were applied to the comparison analysis on the elastic and plastic time history of four structure systems.The dynamic features and anti earthquake performances of the four steel framework structures were compared
