摘要
遗传算法是 2 0世纪 70年代初期基于生物技术而发展起来的一种新型智能优化方法。探讨此方法应用于建筑钢结构设计不仅改变了传统的设计观念 ,而且可以丰富钢结构优化设计理论和方法 ,在经济建设中取得显著效益。建立以重量 (造价 )最小为目标的钢框架结构梁、柱的数学模型 ,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。编制了分析程序 。
Genetic algorithm is a new intelligence optimization algorithm developed from biology at the beginning of the year 1970.The method used in the design of the steel structures not only changed the traditional opinion of design, but also enriched the optimization algorithms of the steel structures.The optimization models of the steel frame with the object functions of minimization weights of the beams and the columns are put forward. The selection, crossover, mutation algorithm of genetic algorithm and parameter coded in binary genes are set up. The structure optimized design program in C is debugged and applied to analyze the steel frame.
