《钢筋混凝土受弯构件单筋矩形断面优化设计及经济配筋率探讨》一文刊载于我院80年第一期《教学与科研》上。该文应用斜量法来解决钢筋混凝土矩形断面的优化设计:通过满足约束条件ψ_2和ψ_3的值,交替梯移和侧移的计算,以逐次迭代的方式求得满足主约束条件ψ_1的最优解。文中以例题说明了斜量法解题的方法和步骤,进行了六十多次的迭代运算后得到了最优解 h。和 A_g 以及相应的最优(经济)配筋率。
The paper “Optimized Design of Single Reinforced Rectangular Sections of Reinforced Concrete Flexural Members and Discussion on the Ratio of Economic Reinforcement” is published in the 80th edition of “Teaching and Scientific Research” in our college. In this paper, the oblique design method is used to solve the optimal design of the rectangular section of reinforced concrete: By satisfying the values of the constraints ψ 2 and ψ 3, the calculation of the alternate steps and lateral shifts, the optimal conditions for satisfying the main constraints ψ_1 are obtained by successive iterations. solution. In this paper, the method and steps of solving the problem by oblique method are illustrated by examples. After more than sixty iterations, the optimal solution h is obtained. And A_g and the corresponding optimal (economic) reinforcement ratio.
