楼梯参与结构整体工作的计算分析
Structural Analysis of Staircase Participated in the Working of Building Structure
【摘要】 本文给出楼梯参与结构整体计算的方法,分析了梯板、梯柱和梯梁在抗震结构中的作用,比较了楼梯布置在不同位置对结构的不同影响。计算结果表明在框架结构中楼梯及其周边构件将承担更多地震力,是结构设计应加强的部位,因此整体分析应考虑楼梯构件的刚度。在剪力墙结构中,若梯板两端分别支撑在两片墙肢上,则楼梯对剪力墙的影响不可忽视。本文通过某实际工程计算结果比较,说明楼梯构件参与结构整体工作的必要性,可供结构设计人员参考。
【Abstract】 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.
