摘要

基于结构遭遇罕遇地震时承载力安全储备与变形安全储备目标,通过对RC框架的震害分析与Pushover分析,得出结构抗震性能及安全性由承载力与变形共同决定的结论,分别从构件层面和结构层面对RC框架结构的延性抗震设计提出了应对措施与设计思路,定量了RC框架抗倒塌的设计及计算,为地震区的建筑物应优先设计成有抗震安全储备的延性结构提供了理论依据.
Based on the loading capacity and deformation safety target of the structure which suffers from a rare,strong earthquake,a seismic damage analysis and a Pushover analysis of the RC frame are made.Results about its seismic performance and safety are obtained;they are jointly determined by the bearing capacity and deformation.The appropriate measures and ideas for the ductility seismic design are put forward,separately from the component level and from the layer face of the RC frame structure.A theoretical basis is also provided for the seismic design of reinforced concrete structures.
