［摘要］以某预制混凝土楼梯为例，介绍了预制混凝土楼梯的设计、计算过程以及节点构造要求。通过对预制混凝土楼梯的计算分析可知，预制混凝土楼梯改变了普通楼梯在地震作用下的受力状态，使楼梯不参与整体结构受力，减轻楼梯在地震作用下的破坏。

Abstract: Taking a certain precast concrete staircase as an example, design, calculation process and joint construction requirements of the precast concrete staircase were introduced. The analysis and calculation results of the precast concrete staircase show that the stress state of the normal staircase under the seismic action is changed by using the precast concrete staircase. The staircase does not get involved in the bearing activity of the overall structure, and the seismic damage is reduced.

Keywords: architectural industrialization; precast concrete staircase; sliding support
