摘要
提出了1种结合灵敏度修正的遗传算法进行结构损伤诊断。在遗传算法计算过程中加入灵敏度修正操作,使遗传过程得以快速收敛并增加了识别准确性。利用4层平面框架进行数值模拟,识别结果表明,本文所提出的结构损伤识别方法比常规遗传算法有效。
A structure identification method based on the genetic algorithm with the technique of sensitivity is developed. The genetic algorithm with the technique of sensitivity can not only reduce the operation time of the program, but also increase the degree of accuracy of identification. A 4 floor plane frame was analyzed by this method. According to the simulation results, the genetic algorithm with the technique of sensitivity is more effective than the conventional genetic algorithm.
