| Abstract: | 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. |
