摘要
本文在前期工作的基础上,建立预应力开孔梁优化模型,采用模糊理论对优化模型的约束边界进行合理的模糊化处理,并讨论研究在不同约束条件下预应力开孔梁的局部最优解。最后,通过综合评判,得到价格性能比最优的满意解。
This paper is concerned with the optimization of the pre-stressed concrete beams with large openings. An optimum model is set up in which the restraints of the model are dealt with the fuzzy theory. The local optimum solutions for different restraints are discussed. The method of fuzzy comprehensive evaluations is adopted in the search of the optimum solutions.
