利用SATWE软件对无楼梯、现浇整体式楼梯及预制分离式楼梯三种方案的框架结构分别进行了振型分解法计算，对比分析了三种方案下结构的周期、水平地震作用、楼层位移及相邻框架柱的内力。分析结果表明，结构设计时应考虑楼梯作用；预制分离式楼梯具有比现浇整体式楼梯更合理的受力性能，对框架结构的影响相对较小。

The paper respectively carries out modal analysis computation for three kinds of frame structures including pure lift frame structure, cast-in-situ integral lift and prefabricated separated stairs with SATWE software,comparatively analyzes structural cycle,horizontal seismic ac-tion,stairs displacement and neighborhood frame column internal-force. The analysis results show that:it is necessary to takes stair action into design consideration;the stress performance of prefabricated separated stair is more rational than that of cast-in-situ integral stairs,which has less impact upon the frame structure.
