采用PERFORM-3 D软件分别对设置消能减震楼梯、滑动楼梯和普通楼梯的框架结构进行罕遇地震下的地震反应分析。结果表明：①消能减震楼梯削弱梯板在顺梯板方向的等效强支撑效应；②与普通楼梯结构相比，消能减震楼梯结构X向楼层剪力减小，层间位移角和顶点位移相差不大；Y向楼层剪力、层间位移角和顶点位移均减小。与滑动楼梯结构相比，消能减震楼梯结构X向楼层剪力相差不大，层间位移角和顶点位移减小；Y向楼层剪力除底层外，其余楼层基本相同，层间位移角和顶点位移减小；③消能减震楼梯结构楼梯间构件损伤程度小于普通楼梯结构和滑动楼梯结构。

This paper presents the comparisons and analyses of seismic responses of three frame structures e -quipped with common stairs , energy-dissipated stairs and sliding stairs under rarely-occurred earthquake .The analysis results indicate that:①the energy-dissipated stairs can weaken the equivalent strong support effect of common stairs along stair-board direction;②compared with the common stairs structure , the structure of incor-porate energy-dissipated stairs is of decreased storey shear forces , along with the similar inter-storey drifts and top displacements in X direction , while universally reduced storey shear forces , inter-storey drifts and top dis-placements in Y direction;however , compared with sliding stairs structure , the structure of incorporate energy-dissipated stairs is of the approximately same storey shear forces , as well as the decreased inter-storey drifts and top displacements both in X direction and Y direction;③the energy-dissipated stairs structure has less damage in stairs components than the common stairs structure and sliding stairs structure .
