摘要:
鉴于近年来国内外连续倒塌事件时有发生，并带来大量的人员伤亡和巨大的经济损失，针对当前影响结构倒塌性能的主要因素及其倒塌破坏机制研究进展进行了综述。结果表明：楼板对结构抗连续倒塌的作用不可忽略；柱失效位置和柱距对结构抗连续倒塌性能具有重要影响；与不考虑节点影响时相比，考虑节点影响时结构的抗连续倒塌承载力降低;填充墙和抗震设计对结构抗连续倒塌能力有益;框架梁上先后作用梁机制（压拱机制）和悬链线机制，板上先后作用压膜机制和拉膜机制，但不同构件作用机制之间的耦合作用和度量指标等研究不足；今后的研究中要加强试验测试工作和倒塌影响的定量化研究,并体现到设计方法中，同时要加强偶然荷载的碰撞冲击对结构倒塌性能的影响研究。
Abstract:
In recent years, progressive collapse often occurred at home and abroad, and accompanied by a large number of casualties and huge economic losses. The research progress of main factors and collapse mechanism that affected the progressive collapse were reviewed. The results show that the contribution of floor on progressive collapse can’t be neglected, and the column failure position and the column spacing have important influence on structural anti-progressive collapse. Compared with without considering the influence of joint, when considering the influence of joint, the progressive collapse resistance of structure will be reduced. The infilled wall and seismic design are beneficial to progressive collapse. In turn, the beam mechanism (the compressive arch mechanism) and the catenary mechanism act on the frame beam, and the compressive membrane mechanism and the tensile membrane mechanism act on the floor. However, the research of the coupling action and measurement index of the mechanism of different components are insufficient. In the next step, the experimental test and the quantitative research about progressive collapse should be strengthened, and the research results should be applied to the collapse design. Meanwhile, it also should be enhanced to study the impact of accidental load on the progressive collapse.
