根据乔汉生屈服准则,得到了板内任一点既满足承载力同时又满足两方向配筋和最小配筋的计算方法。根据一点的最优配筋方法统一考虑一块板,得到了整块板内x向和y向统一配筋时两个方向最优配筋的上、下限值。给出了利用ANSYS在最优配筋的上、下限值范围内寻找整块板最优配筋的计算方法。通过工程实例介绍了对异形板进行最优配筋计算的分析方法和计算过程。
According to Qiaohan Sheng yield criterion, the calculation method that any one point in the plate satisfies both the bearing capacity and the two directions reinforcement and the minimum reinforcement is obtained. According to the optimal method of reinforcement, a piece of slab is considered uniformly, and the upper and lower limit values of the optimal reinforcement in two directions are obtained when the uniform reinforcement in the x and y directions is obtained. The method to find the optimal reinforcement of the whole slab by using ANSYS in the range of the upper and lower limits of optimal reinforcement is given. Through the engineering example, the analysis method and calculation process of optimal reinforcement calculation for profiled slabs are introduced.
