钢筋混凝土抗滑桩必须进行裂缝控制,这与保证足够强度一样重要。抗滑桩属受弯构件,为了使《混凝土结构设计规范》(GB 50010—2010)裂缝宽度计算公式适用于圆截面均匀配筋受弯构件,在分析公式的各个相关因素之后,通过调整它的系数和修改它的参数(σs,ψ,ρte),得出了圆截面均匀配筋受弯构件的裂缝宽度计算公式,构建了一个函数表以简化计算过程。实例的裂缝宽度计算结果表明,建议的方法是简便、合理和可行的。
Reinforced concrete anti-slide piles must be crack control, which is to ensure sufficient strength as important. Anti-slide piles are flexural members. In order to make the formula for calculating the crack width of “Code for Design of Concrete Structure” (GB 50010-2010) applicable to flexural members with uniform circular reinforcement, after analyzing all the relevant factors of the formula, Coefficient and modify its parameters (σs, ψ, ρte), the formula for calculating the crack width of flexural members with uniform circular section is obtained, and a function table is constructed to simplify the calculation process. The calculated crack width of the example shows that the proposed method is simple, reasonable and feasible.
