摘要
参考美国国防部编制的《结构抗连续倒塌设计》(DOD 2009),以12层钢筋混凝土框架为研究对象,基于有限元软件SAP2000,采用拆除构件方法,对角柱和边柱进行连续倒塌破坏效应分析。利用非线性动力分析,研究其抗连续倒塌能力,对结构移柱前后关键构件内力以及塑性铰分布加以对比,进行角柱与边柱连续倒塌的破坏效应分析。
Based on the design process of D0D 2009, examples were provided for the progressive collapse pre- vention design of Chinese frame structures. Using the software SAP2000 of finite element conduct progressive col- lapse analysis for 12 layers of reinforced concrete by alternate path method. Using the nonlinear dynamic analysis to study the progressive collapse resistance. The internal force of key member before and after the removal of the col- umns were compared. Conducting corner and side columns for progressive collapse analysis of the destructive effects.
