对于使用阶段不允许开裂的钢筋混凝土单筋矩形受弯构件,以往一般均先假定断面,然后分别进行强度计算和抗裂度验算。这样往往几经计算仍得不到满意的结果。这里介绍一个简易的方法,可以一次求得断面和配筋的准确结果,供大家参考采用。 For reinforced concrete single-bar rectangular bending members that are not allowed to crack during the service stage, the section is generally assumed in the past, and the strength calculation and the crack resistance verification are performed separately. This often results in less than satisfactory results. Here is a simple method that can be used to obtain accurate results for sections and reinforcements for your reference.
