| 中文摘要 | 为采用改变路径法进行结构连续倒塌分析,研究了该方法所涉及的3个关键问题;建立了采用改变路径法进行结构连续倒塌分析的流程;通过对一个多层平面钢框架连续倒塌分析,对改变路径法采用的线弹性静力分析、非线性静力分析和非线性动力分析方法进行了比较。结果表明:结构初始失效后,由于内力重分布,可能会进一步导致结构损伤;相对于动力分析方法,静力分析方法比较简单,但可能会导致较为保守的结果;静力线弹性分析的结果比静力非线性分析的结果更为保守。; In order to carry progressive collapse analysis of structures by alternate path(AP) method three key problems were studied and flowcharts for performing AP method were set up.By progressive collapse of a multi-story steel plane frame linear elastic static procedure,nonlinear static procedure and nonlinear dynamic procedure of the AP method were compared.The analysis results show: the structure will be damaged further probably because of the redistribution of internal forces after the initial failure;although static analysis procedure is easier than dynamic analysis procedure,it probably yields comparatively conservative results;linear elastic static procedure is more conservative than nonlinear static procedure. |
