The overall analysis method of staircase together with building structure is suggested. The effect of the slab,column,girder of staircase to the whole building are estimated. The effects of staircase placed in different location are compared. The result show,in frame structure,that more earthquake forces may be distributed to the component of stair and other members around it,and that the staircase's stiffness have to take into account. Moreover, in the shear-wall structure,if the slab of staircase is supported by two wall branches,the stiffness effect of the staircase to shear-wall should not be ignored. A practice model has been used to analyze the effect of staircase stiff- ness,and above viewpoints are proved The calculating method and the conclusion can be referred for structural design.
