［摘要］工程结构在偶然极端荷载（如火灾、撞击、爆炸等）的作用下可能会由于局部破坏而引起整体结构的连续倒塌，造成严重的人民生命财产损失以及恶劣的社会影响，结构连续倒塌问题在世界范围内引起了广泛重视。21世纪以来，随着越来越多的专家学者开始关注工程结构的连续倒塌问题，相关研究工作也被陆续开展，并对不同类型结构的连续倒塌失效机理、性能评价及设计方法等方面均进行了深入研究。通过调研21世纪以来国内专家学者在工程结构防连续倒塌领域取得的研究成果，回顾了我国学者在试验研究、数值模拟、理论研究、及工程结构防连续倒塌实践等多方面的贡献及代表性研究成果，分析并归纳了我国目前在结构防连续倒塌领域的科学研究和工程应用现状，最后提出了对我国未来工程结构防连续倒塌研究的展望。

Abstract:The progressive collapse of engineering structures may be initiated by the local failures under accidental extreme loads (i.e., fire, impact, explosion, etc.). It will cause severe casualties, economic loss, and adverse social impact and have attracted widespread attention in the engineering community worldwide. Since the 21st century, more and more scholars started to pay attention to the progressive collapse of engineering structures and a large number of related works were conducted subsequently. To date, there have been many in-depth studies on the failure mechanism, performance evaluation, and design methods of progressive collapse for different types of structures. The research achievements of the domestic scholars in the field of structural progressive collapse since the 21st century were reviewed. The contributions and representative research outcomes on experimental studies, numerical simulations, theoretical analyses, and engineering practice on the topic of progressive collapse are reviewed. The current status of the scientific research and engineering applications in the field of progressive collapse prevention were analyzed and summarized. At last, the prospect of future research on the progressive collapse of engineering structures in our country was proposed.

Keywords:progressive collapse; experimental study; numerical simulation; theoretical analysis; important engineering practice
