| 摘 要： | 遗传算法是建立在自然遗传学机理基础上的参数搜索方法。通过介绍遗传算法在钢筋混凝土梁结构参数求解中的应用,利用遗传算法对钢筋混凝土梁进行优化,建立钢筋混凝土矩形截面梁的满足约束、造价最低优化模型及相应的适应度函数,采用二进制编码,通过执行遗传算法的选择、交叉和变异算子,实现对结构的优化设计,并分析了算例,成功求解了钢筋混凝土梁结构非线性优化设计模型。实例结果表明:该法可以节省时间,优化结果准确并可以降低造价。

| Abstract: | The Genetic Algorithms is a method of searching parameter built up on the basis of natural genetics.A optimized design of reinforced concrete beam with rectangle section is put forward,and then a fitness function is presented to optimize the design,the selection,crossover,mutational algorithm of genetic algorithm and parameter coded in binary genes are set up.The structure optimized design program in C is debugged.The reinforced concrete beam has been optimized by genetic algorithms,and the non-liner optimization design model of reinforced concrete beam construction solved by computer.This method can play an active role in improving the design method,saving time and lowering the engineering cost. |
