摘要 根据工程实际,充分考虑规范规定的约束条件和各项技术标准要求,以力学准则为基础,建立了建筑结构优化模型.提出了一种求解离散变量结构优化设计的拟满应力算法和基本遗传算法结合的混合遗传算法,既发挥了拟满应力算法高效、局部搜索能力强的特点,又发挥了标准遗传算法全局性好的特点.算例结果表明,这种混合遗传算法收敛速度快、精度高,优于标准遗传算法和单一的拟满应力算法,弥补了两种算法的不足,是高效理想的优化方法,可以直接用于多种建筑结构的优化设计. On the basis of the practical structure design of engineering and the mechanics criterion, full consideration has been given to the constraint conditions that the norm stipulates and the demands of various engineering standards, and a model of structural optimization with discrete variables is proposed. Moreover, for structural optimization with discrete variables ,a hybrid genetic algorithm (HGA) composed of the imitative full -stress algorithm (IFSA) and the standard genetic algorithm(SGA) is presented in the paper, taking advantages of powerful local searching capability of IFSA and global searching capability of SGA. The results of exemplification show that HGA, as an efficient optimal method having the advantages of both SGA and IFSA, without their disadvantages, is superior to either one. It can be applied to optimal design of various engineering structures.
