现代民用建筑楼梯多采用板式楼梯，其美观，施工方便。但对于抗震设防来讲，板式楼梯的刚度不如梁式楼梯，如果楼梯板厚度不足，容易在地震水平力作用下产生压弯受力而屈服断裂，造成重大人员伤亡。因此，汶川地震后修订的建筑抗震规范要求楼梯构件必须参与结构模型整体分析。若考虑压弯受力，板式楼梯的楼板要求比较厚，加大自重荷载，浪费材料，不经济。近来一些民用和商用建筑大型楼梯也开始采用梁式楼梯，因为其受力合理，在参与结构整体分析并满足抗震要求情况下，与板式楼梯相比，具有更多的合理性和经济性。
Modern civil building stairs are mostly plate type stairs, which are beautiful and convenient for construction. However, for seismic fortification, the rigidity of slab stairs is not as good as beam stairs. Therefore, the revised seismic code for buildings after Wenchuan earthquake requires that stair components must participate in the overall analysis of the structural model. If the bending force is considered, the slab of the slab stair is required to be thick, so it is uneconomical to increase the self weight load and waste materials. Recently, some large-scale stairs in civil and commercial buildings have begun to use beam stairs. Because of its reasonable stress, it has more rationality and economy than plate stairs when it participates in the overall structural analysis and meets the seismic requirements.
