摘　　要：通过对实际工程中常用的不同结构体系的分析、计算,得到了楼梯对建筑结构整体抗震性能的影响及对周边结构构件受力性能的影响,结果表明,楼梯对于带剪力墙或筒体的竖向抗侧力构件刚度较大的结构体系影响较小,而对于竖向抗侧力构件刚度较小的框架结构影响显著。Through the analysis and calculation on different structure systems which commonly used in the practical engineering, the effect of stairs on the seismic behavior of the whole structure and the effect of stairs on the mechanical behavior of the surrounding structure components can be obtained. The results indicate that the structure systems which have large stiffness vertical lateral force- resisting members such as shear wall or core wall are less affected by the stairs, while the frame systems with less stiffness vertical lateral force-resisting members are affected significantly by stairs.
