从现行钢筋混凝土板式楼梯设计方法分析,楼梯设计时仅计入了恒载和可变荷载,未考虑地震作用的影响,应在设计计算时,将楼梯参与整体计算以考虑地震作用。有学者给出了新型楼梯参与结构整体计算的方法,把楼梯当做斜梁来考虑其刚度。并分析了楼板、梯柱和梯梁在抗震结构中的作用,同时比较了楼梯布置在不同位置对结构的不同影响。
From the analysis of the design method of existing reinforced concrete slab stairs, the design of staircases only includes constant load and variable load. Without considering the effect of earthquake, stairs should be involved in the overall calculation to consider the earthquake effect. Some scholars have given a new type of stairs to participate in the overall structure of the calculation method, the staircase as a skew to consider the stiffness. The effect of floor slab, ladder column and ladder beam in seismic structure is also analyzed. At the same time, different influences of the staircase arranged in different positions on the structure are compared.
