摘要
在进行梁式楼梯的梯板配筋设计时,设计人员一般采用教材中推荐的近似算法进行正截面抗弯承载力设计。从正截面抗弯承载力的基本假定出发,推导出了该构件精确算法的一般公式,通过算例演算证明,近似算法的配筋运算结果较精确算法偏大很多,建议设计人员在工程中使用精确算法进行设计,使设计经济合理。
In the process of reinforcement design in slab of beam-type stairs, designers usually adopt approximate calculation method recommended by text books to design bending-resistance bearing capacity of normal section. Based on the basic assumptions of bending-resistance bearing capacity of normal section, this paper deduces the general formula of precise calculation method and verifies with an example. By comparison, the reinforcement of approximate calculation is more excessive than that of precise calculation. Therefore, the precise calculation method can be used by designers to make designs reasonable and economic.
