【摘要】 本文分别根据GSA(General Services Administration)2003规范和我国《高层建筑混凝土结构技术规程》JGJ3-2010规范下的线性静力拆除构件分析方法对包头市某框架结构教学楼进行了抗连续倒塌对比分析,由于两种方法的加载模式和评估指标均不相同,所以不能由理论计算比较两种方法的分析结果.本文通过具体对一栋结构的抗连续性倒塌分析得到:我国规范的线性拆除构件法对结构的抗连续性倒塌分析要比GSA规范下的分析方法得到的结果更保守.更多还原

【Abstract】 The continuous collapse resistance of a frame structure in Baotou was analyzed using the linear static demolition component methods according to the GSA(General Services Administration) 2003 specification and the Technical specification for concrete structures of tall building JGJ3-2010 specification in our country.Due to the difference in the load model and the evaluation index between the two methods,the results of the analysis with the two methods should not be compared by theoretical calculation.Through analyzing the progressive collapse resistance of a concrete structure,the conclusion is drawn that the linear static demolition component method of China for the analysis result of resisting progressive collapse is more conservative than the analytical method based on GSA specification.更多还原
