INTELLIGENT OPTIMAL DESIGN BASED ON ENERGY ANALYSIS AND SEISMIC DAMAGE PERFORMANCE
-
摘要: 在基于能量分析法的地震损伤性能控制设计的基础上，通过引入改进的遗传算法，提出了基于能量分析法的地震损伤性能智能优化设计，并编制了相应的优化程序。算例分析表明，提出的智能优化设计方法及其编制的优化程序是合理可行的，可以自动实现结构的优化设计;提出的改进的遗传算法与一般遗传算法相比具有较好的收敛性能。Abstract: A method of intelligent optimal design based on seismic damage performance and energy analysis is presented onthe base of the performance- based seismic control design based on energy analysis developed in reference [2] and animproved genetic algorithm. The programs of genetic algorithm and the improved genetics algorithm are developed. Thefeasibility and accuration of the method of intelligent optimal design are verified through an example. And the convergence ofthe improved genetic algorithm is better than that of genetic algorithm.
