| 摘 要： | 本文论述了采用遗传算法进行结构优化设计时遇到的诸如计算量大、早熟收敛和边界探索不足等棘手问题，提出了三个解决对策，编制了计算程序，其在桥梁抗震代化设计中的应用效果表明，改进后的遗传算法不但提高了计算速度，而且在尽可能短的时间内找到最好的优化解。

| Abstract: | This paper is concerned with some thorny issues of the Genetic Algorithm when it is applied to structural optimum design Suggestions are made and incorporated into the Genetic Algorithm (GA) to deal with the problems of excessive computational cost premature convergence and poor searching ablity along boundaries . The improved GA is adopted to conduct optimum design of bridges under earthquake . It is shown that the improved GA is efficient and reliable . |
