Through applying common finite element analysis software SAP2000 ,the paper compares six-story steel reinforced concrete frame structure with and without stairs,briefly studies the impact of stairs upon structural stress performance and integral seismic performance under the earthquake,carries out elastic seismic response by applying standard CQC for the structural model,and finally draws some conclusions through computation.%采用通用有限元分析软件SAP2000对带楼梯和不带楼梯的钢筋混凝土六层框架结构进行了分析比较，简单研究了地震作用下，结构存在楼梯构件对该结构受力性能和整体抗震性能的影响，同时采用规范规定的振型分解反应谱法（ CQC）对该结构模型进行弹性地震反应，通过计算分析得出了一些结论。
