摘要
地震时,楼梯是重要的逃生通道。但关于地震作用下楼梯与框架共同工作方面的研究还很少,文章采用结构有限元软件Midas/Gen,对一个6层钢筋混凝土现浇板式楼梯框架办公楼模型进行分析,对模型在地震作用下的受力情况进行了详细研究,与传统楼梯设计方法(楼梯间结构不考虑地震作用,结构处楼梯间开洞)结构地震反应做对比。结果表明:考虑楼梯参与结构整体计算会增加结构的抗侧刚度,且结构扭转效益增大,总体对结构不利。
he researches on performance of frames with stairs under earthquake are scarce.In this paper,an analysis of a six-floor reinforced concrete frame structure with cranked slab stairs was carried out using the finite element software Midas / Gen for model structure.Compare with the traditional design method of stairs （ staircase structure is not considered earthquake ,the structure at the stairwell openings） seismic response.The results showed that： the whole structure into account in calculating the stairs will increase the lateral stiffness of the structure, increase efficiency and torsion ,the overall structural disadvantage.
