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
