| 摘 要： | 对按我国现行规范设计的一栋带转换梁的高层建筑结构进行抗连续倒塌性能分析,结果表明：支承转换梁的角柱或边柱一旦失效,结构就会发生连续倒塌;支承转换梁的内柱失效时,由于梁的悬链线作用,结构未发生连续性破坏,但有多根梁进入了塑性状态,结构发生连续倒塌的可能性较大。针对上述3种情形,提出不同的应对措施,以提高结构抗连续倒塌能力。

| Abstract: | It is analyzed in this paper on progressive collapse resistance ability of tall building structures with transfer girdes that are designed accroding to the current design code.The results show that once the corner or edge column of supporting transfer girdes is failed,the structure will collapse in a row.If the inner column of supporting transfer girdes is failed,the risk of the structure collapse is high.Aim at the above results,different strategies and means of improving progressive collapse resistance ab... |
