摘　　要：结构连续倒塌会造成严重生命财产损失,高层建筑在偶然作用发生时应具有适宜的抗连续倒塌能力。采用《高层建筑混凝土结构技术规程》(JGJ 3—2010)的拆除构件法和附加侧向偶然作用法计算分析了海口双子塔-南塔结构抗连续倒塌性能,结果表明剩余构件的应力比满足抗连续倒塌要求;动力弹塑性计算方法复核验算结果表明,结构因构件拆除而产生的动力效应并不明显,剩余构件均未出现塑性行为。两种方法均表明海口双子塔-南塔结构具有良好的冗余度和抗连续倒塌能力。The progressive collapse of the structure causes serious casualties and property losses. High-rise buildings should have appropriate ability to resist progressive collapse when accidental action occurs. The anti-progressive collapse ability of the Haikou Twin Towers-South Tower was calculated and analyzed by using the demolition member method and the additional lateral accidental action method in the code of Technical specification for concrete structures of tall buildings(JGJ 3—2010). The results show that the stress ratio of the remaining components satisfies the requirement for anti-progressive collapse. The dynamic elastic-plastic calculation method was used to check the calculation, and the results show that the dynamic effect of the structure due to component demolition is not clear and there is no plastic behavior of the remaining members. Both methods show that the Haikou Twin Towers-South Tower has good redundancy and ability to resist progressive collapse.
