历次震害表明,建筑物在地震作用下的倒塌是造成地震灾害的主要原因,如何合理提高建筑物的抗倒塌能力是目前迫切需要解决的问题,也是对结构进行抗地震倒塌设计的基础。采用抗倒塌储备系数（CMR）方法,对钢框架的整体抗倒塌能力进行分析,通过结构的抗倒塌储备系数来衡量结构的抗倒塌能力。通过提高结构的延性和超强来提高结构的抗倒塌能力,考虑了梁对柱的约束程度、柱轴压比对结构抗倒塌能力的影响。

Previous earthquake damage shows that the collapse of buildings under the earthquake is the main reason for the earthquake disaster. The way to improve the building＇s collapse resistance is a problem needed to be solved urgently, which is also a basis of the structural collapse resistance design. According to ＂Code for Design of Building＂, this paper analyzed the overall collapse resistance of steel frames by CMR analytical method, and measured the collapse resistance of the structure through the collapse margin ratio. The increase ot the ductility and overstrength will improve the collapse resistance of the structure. The paper also considered the constraint on the degree of beam column and the effect of the axial compression ratio on the collapse resistance of the structure.
