REVIEW OF THE KEY ELEMENT FOR PROGRESSIVE COLLAPSE OF STRUCTURES
-
摘要: 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。Abstract: The progressive collapse analysis of structures becomes a hotspot for study over the world. The search of the key element is an important task for the alternative path method. On the basis of comparing the methods for the estimate of important elements,some conclusions were discussed. Furthermore,the three requirements for the method to judge the key elements of a structure were also given.
