| 摘 要： | 探讨了遗传算法在公路桥梁钢筋混凝土受弯构件优化设计中的应用，并且针对简单遗传算法存在“早熟收敛”的缺陷，采用大变异操作来避免产生局部最优解。数值实验证明，与常规优化方法比较，遗传算法能从搜索空间中多点出发进行探索寻优，寻优过程中仅涉及适应度函数的计算与评价，能很好地解决结构优化设计问题。

| Abstract: | Optimum design of reinforced concrete flexural member based on Genetic Algorithm has been
carried out.An improved approach called big mutation operation is proposed to avoid local
optima.The numerical results show the effectiveness of Genetic Algorithm. |
