为了评估多层钢框架在不同抗震设防标准下的抗倒塌能力,按我国现行规范设计了5个多层钢框架结构,采用美国ATC委员会提出的CMR分析方法对钢框架结构倒塌储备能力进行分析,得出了钢框架算例的相应倒塌储备系数和倒塌概率曲线。分析了不同抗震设防标准多层钢框架IDA计算的结果,评价了不同抗震设防烈度多层钢框架的抗倒塌能力和抗倒塌安全储备,讨论了不同抗震设防标准多层钢框架的倒塌概率,并且提出了抗震设防标准的有关建议。

In order to evaluate the seismic collapse margin of multi-story steel frames with different seismic forti- fication levels, this paper analyzes five different steel frames designed according to "Code for Seismic Design of Building" (GBS0011-2001) by CMR analytical method which was proposed by ATC (Applied Technology Coun- cil) committee of America, and gets the corresponding collapse margin ratio and the collapse possibilities under different ground intensities. In this paper, the collapse-resistant capacities and safety margins against collapse of multi-story steel frames with different seismic fortification levels are quantitatively evaluated, with a collapse fragility analysis based on an incremental dynamic analysis frames with different seismic fortification levels is discussed, design. (IDA). The collapse possibility of multi-story steel and suggestions are proposed to improve the current
