摘　　要：首次将遗传算法 (GA)引入双层圆柱面网壳结构的优化设计中 ,实现了对网格尺寸、结构厚度、矢跨比的同步优化。编制了相应的程序 ,并进行了大量的算例分析 。We firstly proposed that genetic algorithm could be used in the optimization design of double layer cylindrical latticed shell,which realized the synchronous optimization of the rise/span ratio,grid size and the vault thickness. Through compiling programs and analyzing samples, we have proved the excellent performance of this method.
