| Abstract: | Based on mode shape,a new parameter is put forward-mode shape curvature ratio,for detecting structure damages.And it is also the input vector of the neural network.Then through finite element analysis and calculating the training and forecasting samples are got for the network.The neural network can identify the damage location and degree of the structure.It proves that this method is simple and valid,value to prompt and application. |
