Abstract

When using vibration response and deep learning for structural damage identification, the problems such as requiring more data of measuring points, low accuracy of damage identification, and over-fitting of the network will be encountered. Therefore, a novel structural damage identification method based on Convolutional Neural Networks ( CNN ) -Gated Recurrent Unit ( GRU ) parallel neural network are presented in this paper. Firstly, the Generalized S Transform ( GST ) is performed on the measured response signal to obtain the GST time-frequency diagram. Then, CNN and GRU are used to extract time-frequency features and temporal features from time-frequency diagrams and response signals, respectively. The time-frequency features and temporal features are spliced and input into the fully connected layer and Softmax classifier for structural damage identification. The verification results of the model test data of offshore wind power supporting structure under displacement excitation show that the proposed method only needs the response signal of one measuring point and has higher identification accuracy and efficiency than other similar methods.
