［摘要］建筑結(jié)構(gòu)在意外事件時的連續(xù)倒塌已成為嚴重威脅公共安全的重要問題。參考美國國防部編制的《結(jié)構(gòu)抗連續(xù)倒塌設計》（DoD 2005）提供的設計流程，對按照我國現(xiàn)行規(guī)范設計的8層鋼筋混凝土框架進行了連續(xù)倒塌仿真分析，研究了其抗連續(xù)倒塌能力。并應用拉結(jié)強度法和拆除構(gòu)件法，對該框架進行了抗連續(xù)倒塌設計，建立了將國外規(guī)范中的抗連續(xù)倒塌設計方法應用于我國框架結(jié)構(gòu)的設計實例，并指出了其中存在的一些問題。

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 problems when applying foreign codes to Chinese buildings are pointed out.

Keywords:progressive collapse; concrete frame; tie force method; alternate load path method
