摘要
采用SAP2000(V11.0.8 Advanced C)有限元分析软件,对12层钢结构框架建筑进行基于性能的Pushover能力谱法分析,考虑了纯框架、中心支撑框架、偏心支撑框架、隅撑支撑框架4种结构体系,结果表明:相对于纯框架和中心支撑框架,偏心支撑框架和隅撑支撑框架具有更优越的力学性能和更好的经济效益,设计中宜优先考虑使用。
Adopting SAP2000(V11.0.8 Advanced C)finite element analysis software,using design based on performance Pushover capacity spectrum method,the structural scheme of twelve stories steel frame buildings are analysised,having considered the four structural schemes of Moment Resisting Frames(MRF),Centre Braced Frame(CBF),Eccentric Braced Frame(EBF),Knee Braced Frame(KBF) are compared.The results indicate that the EBF and KBF possess of much more favorable frame performance and economic benefit than MRF and CBF,and should give priority to use them in practical design.
