摘要
楼梯作为建筑物中层间垂直交通用的构件,在建筑使用功能上有极大的用途。工程设计中就出现设计者为加强楼梯的安全储备或者在计算楼梯梯板的挠度时对梯板加厚的情况,表面是看是增加了楼梯的抗力,本质上却忽略了结构概念设计的基本思路。因此,本人通过举例计算分析,楼梯结构设计建议采用设置滑动支座来消除其对整个结构体系的不利作用,梯板挠度计算时应考虑踏步的有利影响,仅供同行结构设计人员探讨。
As a component of vertical traffic between buildings,the stairs have great use in the function of the building.Designers in order to strengthen the safety stairs or in the reserves of the slab deflection calculation of stair slab thickening appeared in the engineering design,the surface is increased stairs resistance,essentially ignoring the basic ideas of structural conceptual design.Therefore,through the example of calculation and analysis,the design of the structure of the stairs suggested the use of sliding bearings to eliminate its adverse effects on the entire structure of the system,only for peer structural designers to explore.
