建筑结构的连续性倒塌分析已成为国内外的一个研究热点,变换荷载路径法(AP法)的一个重要内容是确定结构的重要构件。在对现有结构重要构件判断方法分析比较的基础上,对其进行归纳总结,并给出了结构重要构件判断方法所必须具备的三个条件。 Continuity collapse analysis of building structure has become a hot research topic both at home and abroad. An important part of the method of changing load path method (AP method) is to determine the important components of the structure. Based on the analysis and comparison of the judgment methods of the important structural components of existing structures, this paper summarizes them, and gives the three conditions that must be possessed to judge the important structural components.
