摘要(Abstract):

结构连续倒塌越来越受到工程界的关注,已成为一个研究的热点。对国内外结构连续倒塌分析与设计方法的研究现状及存在的问题进行了归纳和总结,指出了连续倒塌分析可分为两种类型,即倒塌风险评估和倒塌仿真,并对其中涉及的关键问题(主要是破坏准则和分析方法)进行了评述;提出了连续倒塌设计应由概念设计及计算设计两部分组成。
At present,the progressive collapse of structures attracts more and more attention in engineering field and becomes a hotspot for study.The present research achievements and existing problems of analysis and design approaches for progressive collapse of structures are summarized.It is pointed out that the progressive collapse analysis methods can be classified as collapse risk evaluation and collapse simulation and the related key problems such as damage rule and analysis method are discussed.It is proposed that design for progressive collapse should include conceptual design and computational design.
