| Abstract: | In this paper, the choice of sensitive parameter of stiffness or flexibility is discussed, and it is proved that the exact value of flexibility matrix may be obtained from some lower model parameters. So a new method combining flexibility parameter and the neural networks for the structural damage detection is proposed. In the end, a numerical example is given to show the effectiveness of the proposed method. |
