中文摘要	1968年英国 Ronan Point 公寓倒塌事件以来,建筑结构的抗连续倒塌问题在国际上受到广泛关注,世界各主要国家均制定了结构抗连续倒塌的设计规范和具体设计方法,而我国目前相关研究还较少。本文介绍了清华大学土木工程系近期在钢筋混凝土框架结构抗连续倒塌方面开展的一系列研究工作。本文简要介绍了国外抗连续倒塌设计规范的主要设计方法和分类设计体系。然后对拆除构件设计法和拉结强度设计法进行较为深入的探讨。首先,对基于非线性动力分析的拆除构件设计法进行了设计验证;然后,对基于线弹性静力分析的拆除构件法的原理和设计参数进行了分析和验算,并提出适合我国工程结构的设计参数;最后,验证并分析了国外规范拉结强度设计法应用于我国工程时的不适用性及其原因,并对国外规范拉结强度设计法的基本拉结强度的计算模型所存在的不足进行了改进,提出了考虑空间传力路径等因素的拉结强度设计法,并通过算例进行了设计验证。; Since the collapse of the Renan Point Tower in United Kingdom in 1968,the progressive collapse resistance of building structures has attracted a worldwide spread attention.Main countries in the world developed their own codes and engineering design methods for building structures to resist progressive collapse,but the related research is still lack in China.This paper presents a series of researches of civil engineering department in Tsinghua University on progressive collapse resistance of reinforced concrete frame structures.The major design methods and classification design system in foreign codes are summarized.And then the alternate path(AP) method and tie force(TF)method in foreign codes are studied more deeply.Firstly,the nonlinear dynamic AP method is applied to a Chinese typical concrete frame structure to show its' effectiveness.Secondly,the principle and design factors of the linear static AP method are also analyzed and verified,and moreover,design factors suitable for Chinese structures are suggested.Finally,the application of TF method on a Chinese structure shows its inapplicability.And then,based on the analysis and improvement for calculating model of TF method,this paper suggests a TF method considering space load paths which is verified by design.
