板式楼梯的优化设计方法

Optimization design method of slab staircase

通过考虑梯梁对平台板和梯段板的约束作用并将楼梯视为连续板,推导出楼梯内力计算公式。对普通板式楼梯受力模型进行简要分析比较,得出较精确楼梯设计方法,使其经济美观,可为设计提供参考。

By considering the constraint effect of the stair beam on the platform slab and the flight slab,and the stair is regarded as a continuous slab,the internal force calculation formula of stairs is deduced.This paper makes a brief analysis and comparison of the stress model of common slab stair,and obtains a more accurate stair design method,so as to make it economical and beautiful and provide reference for design.
