摘　　要：自1968年英国Ronan Point公寓倒塌事件以来,国外已经对连续倒塌问题进行了四十多年的研究,并编制了相关设计规范;而我国规范目前尚未规定详细抗连续倒塌设计方法。参考美国公共事务管理局编制《联邦办公楼和大型现代建筑连续性倒塌分析和设计指南》(GSA2003)提供的设计方法和流程,利用ABAQUS有限元软件,采用拆除构件法,对一榀钢框架进行了连续倒塌分析,得出此框架满足抗连续倒塌相应要求以及相应的受力特性和位移特点。Since the collapse of the Ronan Point Tower in United Kingdom in 1968,North America and Europe have conducted more than 40 years of research to this issue and developed corresponding design codes and design guides.However,codes in china have not yet proposed in detail on the resistance of progressive collapse.Hence,based on the design methods and processes proposed in GSA guidelines and finite element ABAQUS software,using Alternate Path Method,the capacity to resist progressive collapse of a steel frame is analyzed.Finally,this frame has been resistance to progressive collapse capabilities,and mechanical property and displacement characteristics.
