摘　　要：本文提出了关于悬索结构形态优化时设计变量的选取和优化目标的确立方法.通过对基于遗传算法的悬索结构形态优化的研究,表明遗传算法应用于柔性结构优化的可行性和收敛性,且其具有全局搜索能力强、运算稳健性好等优点.The method of choosing design variables and optimum objective function in form optimization of suspended cable roofs was put forward in this paper. Examples showed that the genetic algorithm was feasible and convergent in form optimization of flexible structures, and it had many merits such as strong holistic searching capability and good operation steadiness.
