Abstract :The key issue of progressive collapse (PC) design method is to determine the PC resistance demand of the structures with members removed due to accidental action.
摘要 ：结构抗连续倒塌设计方法的关键是确定因偶然作用导致局部构件失效后剩余结构的连续倒塌抗力需求。
It is proposed that design for progressive collapse should include conceptual design and computational design.
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。
Attention should be paid to the design for prevention of progressive collapse caused by local failure due to abnormal loading in all types of structures.
