半刚接钢框架内填RC墙结构超强及强度折减系数研究

Overstrength and Strength Reduction Factor of Partially Restrained Steel Frame With RC Infill Walls

基于半刚接钢框架内填RC墙结构(简称PSRCW)的性能试验结果,分析了延性破坏的PSRCW结构的超强能力,并结合等倒塌原则建立了PSRCW结构的位移延性系数.采用Newmark-Hall提出的Rμ-μ-T经验公式,给出了罕遇地震水准下PSRCW结构的延性折减系数以及强度折减系数.为了同我国现行抗震规范相协调,还给出了偶遇地震水准下PSRCW结构的强度折减系数,为PSRCW结构的合理抗震设计提供参考.

According to performance experiment of partially restrained steel frame with RC infill walls(PSRCW),the overstrength behavior has been analyzed,and ductility reduction factors of PSRCW is proposed based on equal collapse rule.Rμ-μ-T empirical formula from Newmark-Hall was used to deduce ductility and strength reduction factors of PSRCW under the rare level of earthquake.In order to make the research be consistent with seismic code,this paper also gives ductility and strength reduction factors of PSRCW under...
