| 摘 要： | 结构的连续性倒塌一直是土木工程领域关注的焦点,现阶段各个国家关于连续倒塌的规范在设计方法以及具体规定上均有所差异。回顾了抗连续倒塌研究的发展历史,梳理了国内外抗连续倒塌设计规范中的不同规定,对国内外抗连续倒塌规范的设计方法进行了归纳总结,比较了各国规范安全等级划分方式以及验算时荷载组合的异同,并对破坏发生范围的界定做了详细对比,为将来形成统一的规范提供一定参考。

| Abstract: | The structural progressive collapse has always been the focus of attention in the field of civil engineering.There are lots of differences in the design methods and specific provisions of the codes for progressive collapse designation in their own countries at current state.This paper reviews the development history of progressive collapse resistance,sorts out the different provisions of codes for progressive collapse resistance design and summarizes the design methods of progressive collapse resistance codes at home and abroad.A comparative study on the similarities and differences of safety classification methods and load combinations in national codes,and a detailed comparison of the definition of the range of failure is conducted.The results can provide a reference for the preparation of unified codes for progressive collapse resistance design in the future. |
