【摘要】 高层建筑结构抗连续倒塌危害严重。介绍了拆除构件法的基本原理,并以某超高层建筑为例利用此方法,采用SAP2000和Perfom-3D软件进行了静力线性分析和动力非线性分析,对其抗连续倒塌性能进行了评估,并根据计算结果提出相应的加强措施。研究表明:按照国家规范设计的低烈度区超高层建筑,已经具有良好的抗连续倒塌性能,无需采取额外措施进行抗连续倒塌加强。
【Abstract】 The progressive collapse of super-high building will cause serious consequence.After fundamental briefly introduced,the Alternate Path Method is applied in a super-high building to evaluate its capacity of resisting progressive collapse.Both static linear analysis and nonlinear dynamic analysis are conducted by commercial software,SAP2000 and Perform-3D.And measures are proposed according to conclusions of the evaluation.It shows that super-high buildings in areas with low seismic fortification intensity,designed by present codes,have adequate capacity of resisting progressive collapse,and any extra measures to improve the capacity are unnecessary.
【Key words】 super-high building; progressive collapse; demolition component method; SAP2000; Perform-3D;
