钢筋混凝土框架结构优化的拟满内力遗传算法
|
摘要
为解决遗传算法在结构优化过程中易出现早熟收敛的问题,采用C++Builder软件编制一种适用于钢筋混凝土结构优化的新方法,该方法以结构的造价为目标,将遗传算法与拟满内力法相结合,对多层钢筋混凝土框架结构进行优化.研究结果表明:拟满内力遗传算法的优化结果优于遗传算法与拟满内力算法的结果.既可发挥遗传算法全局优化好的优势,又可利用拟满内力法善于局部优化的特点,可解决多变量、多约束的钢筋混凝土结构优化问题,是一种有效且可行的优化设计方法.
In order to solve the problem of premature convergence of genetic algorithm in optimization process, A new method for optimizing reinforced concrete structures is developed by using C++ Builder software. This method takes the structure cost as the objective, combines genetic algorithms with Imitative full internal force method, and optimizes multi-layer reinforced concrete frame structure. The results show that the optimization results of imitative full internal force genetic algorithm are better than those of genetic algorithm and imitative full internal force genetic algorithm. It can be used to solve the problem of multi-variable and multi-constraint optimization of reinforced concrete structures by using the characteristics of the full internal force method, which is good at local optimization. It is an effective and feasible optimization design method.
