| 摘 要： | 建筑结构在意外事件时的连续倒塌已成为严重威胁公共安全的重要问题。参考美国国防部编制的《结构抗连续倒塌设计》(DoD 2005)提供的设计流程,对按照我国现行规范设计的8层钢筋混凝土框架进行了连续倒塌仿真分析,研究了其抗连续倒塌能力。并应用拉结强度法和拆除构件法,对该框架进行了抗连续倒塌设计,建立了将国外规范中的抗连续倒塌设计方法应用于我国框架结构的设计实例,并指出了其中存在的一些问题。

| Abstract: | Currently,the progressive collapse of building structures due to accidents has become a serious threat to the public safety.Mainly referring to the design process proposed in DoD 2005,the capacity to resist progressive collapse of a typical Chinese 8-story reinforced concrete(RC) frame is analyzed.Then the frame is redesigned with the tie force method and the alternate load path method proposed in DoD 2005 to provide examples for the progressive-collapse-resistance design for Chinese engineers.And some prob... |
