摘要
采用替代路径法对华为上海基地多层吊楼结构进行抗连续倒塌设计。根据结构受力特点,确定了计算模型及去除的关键构件位置。材料强度设计值、荷载组合以及构件失效准则参考美国和我国相关规范中的要求。吊楼整体或大部坠落则认为结构破坏。计算表明,由于常规设计时吊楼具有合适的冗余度和较高的安全储备,吊楼通过了抗连续倒塌验算。
A local suspension structure was designed to resist progressive collapse by means of alternate path method.The structural model and the removal locations of the key elements were determined according to the conceptual analysis.The design strength of the materials,loads combination and failure criteria for structural elements followed the provisions addressed in American and Chinese design codes respectively.The results show that,the structure meet the design requirements of resisting progressive collapse due to the appropriate redundancy degree and relative high reliability of the structure in original design.
