| 摘 要： | 针对结构优化设计问题的特点，提出了两级优化－进化算法的优化策略。以一个12层框架结构的优化设计为例，测试了该优化策略的效率，与单独采用进化算法相比，该优化策略在保证优化结果精度的前提下能大幅度提高优化的效率，是一种较好的工程优化方法，虽然以多层框架结构为优化对象，但提出的优化策略完全适用于其它类型结构的优化问题。

| Abstract: | A 2 level optimization and evolutionaryprogramming optimization strategy is given,so far as the characteristics of structure optimization design are considered .Using the optimization strategy given,we solved the optimization design of a 12 story frame .It is found that using this optimization strategy is more efficient than using evolutionary programming only,and the solution has enough precision.The optimization strategy given is a satisfactory engineering optimization method.Although a multi story frame is used as opimization object,the optimization design strategy given can be applicable to the optimization design for other types of structure. |
