| 摘 要： | 建筑结构的倒塌可分为两种模式:建筑物侧向增量倒塌与竖向连续倒塌。本文论述了建筑物结构失效模式的如何辨识以及侧向倒塌能力点确定准则的相关研究进展。介绍了现有的连续倒塌研究方法,尤其是基于备用荷载路径的竖向非线性动力分析方法。为建筑结构整体抗震可靠度研究以及结构抗震性能评定与设计提供参考。

| Abstract: | The collapse of building structure can be analyzed with two modes:lateral incremental collapse and vertical progressive collapse.The research progresses of failure mode identification and lateral collapse capacity point determination criteria of building structures are discussed.Focuses are placed on the analysis of the existing structural progressive collapse design methods,especially the vertical nonlinear dynamic analysis method based on the standby load path.It provides a reference for the study of the overall seismic reliability of the structure and the evaluation and design of the seismic performance of the structure. |

| Keywords: | seismic vulnerability lateral collapse continuous collapse IM-DM criteria alternate load path method |
