摘　　要：本文给出了基于损伤性能的抗震结构最小造价设计数学模型，并分析了其特点和难点，然后把优化的数学模型转化为人工进化模型，用遗传算法实现了抗震结构的智能优化设计。研究结果表明，遗传算法是实现结构智能设计的有效途径，具有广阔的应用前景。In this paper, the mathematical model of minimum-cost design of aseismic structures based on damage performance is given, and its characteristics and difficulties are analyzedThen the mathematical model of optimization is translated into an artificial evolutionary model,and the intelligent optimum design of aseismic structures is realized via genetic algorithms. The results obtained in the paper show that genetic algorithms is an effective way to attain the goal of structural intelligent design, and its application prospect appears to be highly promising.
