摘　　要：提出了一种综合运用数学规划法、满应力准则法和遗传算法的混合优化设计算法,解决预应力钢结构优化设计中两类变量、三个方面的优化设计问题,分别为连续变量、非连续变量和形状优化、截面优化、预应力优化。通过算法原理分析和算例计算,表明该优化算法有一定的应用价值。A mixed optimal design algorithm is put forward, which applies mathematical planning law, full stress criterion method and genetic algorithm. This algorithm can be used to solve optimal design of prestressed steel structures, including two kinds of variables （continual variable and discrete variable） and three kinds of optimizations （shape optimization, section optimization and prestress optimization）. Finally, arithmetic principle is analyzed and numerical example is calculated by the program, thus proving that the optimal design algorithm can be used.
