为了研究楼梯刚度对框架结构抗震性能的影响，建立了考虑和未考虑楼梯刚度的框架模型，并对其进行了小震作用下的弹性分析，结果表明：楼梯刚度会明显提高结构的刚度和楼层剪力，减少结构的层位移和层间位移；楼梯的非对称布置会引起结构平面扭转，影响结构的抗震性能。

In order to study the effect of stair stiffness on seismic performance of the frame structures,a frame model considering and without considering the rigidity of stairs is established. Through the elastic analysis of the small earthquake,the results show that:the stiffness of the stairs can obviously improve the stiffness and the floor shear of the structure,reduce the structural displacement and the displacement between the layers. The structural plane torsion caused by the asymmetric layout of the steps will influence the anti-seismic performance of the structure.
