用动态规划方法优化肋形结构的截面尺寸

当整体式单向板肋形结构根据使用要求进行了梁格布置后,确定板厚以及次梁与主梁的高度以使结构造价最低的最理想方法就是进行优化设计。本文用动态规划方法建立了这种结构优化设计的数学模型,并给出了优化的目标函数及在优化过程中需要遵守的约束条件。

The Optimization of the Dimensions of the Beam-and-girder Construction hy Means of Dynamic Programming

When the arrangement of beams and girders of a monolithic one-way solid-slab beam wand girder construction has been determined, it is an idealy method to utilize the optimum design for selecting the thickness of slabs and the depths of beams and girders to retuce the cost to a minimum. In this paper, a mathemedical model for the optimum design of this construction is built up by means of dynamic programming, and the objective function of optimization and the constraints that must be observed in the optimum process are also given.
