摘　　要：随着经济的发展,由突发事件造成的连续性倒塌事故越来越多,经过很长一段时间的研究,国外学者已取得了突破性的进展。然而为了计算模型的简化,很多人在研究过程中往往忽略了楼板对抗连续性倒塌的影响。本文利用非线性静力分析法,基于拆除构件法,对一六层规则的框架结构进行分析,通过研究结构的位移及内力,进一步探讨楼板对结构抗连续性倒塌的有利影响。With the development of economy,more and more progressive collapse accidents are caused by sudden accidents.After a long period of time,foreign scholars have made breakthrough progress.However,in order to simplify the calculation model,many people often neglect the effect of the floor slab on the progressive collapse.In this paper,the nonlinear static analysis method is used to analyze the frame structure of 16 layers based on the method of removing the component.By studying the displacement and internal force of the structure,this paper further discusses the beneficial effect of the floor slab on the progressive collapse resistance of the structure.
