| 摘 要： | 为研究楼梯构件对框架结构抗震性能的影响，建立了考虑楼梯构件的精确分析模型，首先对弹性分析的结果进行了对比分析；进一步的Pushover分析结果表明：考虑楼梯构件的框架结构在强震作用下塑性变形机制与常规的框架计算模型有较大的差别。最后．文章给出了考虑偻梯构件影响的抗震框架结构的设计建议。

| Abstract: | In order to study the seismic performance of the RC frame considering the influence of stair element,the accurate Etabs analysis model is established.Comparison is carried out between FEM results.The results of pushover analysis show that the stair element affect the ductility of the frame distinctly.At last,we made suggestions about the optimum design of stair area of RC frame. |
