Abstract

This chapter explores the application of a hybrid deep learning model, SE-1DCNN-LSTM, for classifying structural damage in steel frames using acceleration data. The model integrates a one-dimensional convolutional neural network (1DCNN) with a Squeeze-and-Excitation (SE) mechanism and a Long Short-Term Memory (LSTM) module to capture both spatial and temporal features effectively. The study utilizes the QUGS acceleration dataset, collected from a steel frame structure under various damage scenarios, to train and evaluate the model. The results show that the SE-1DCNN-LSTM model achieves higher accuracy and improved generalization compared to a conventional 1DCNN-LSTM model. The SE mechanism enhances feature discrimination by adaptively assigning weights to different data channels, focusing on the most critical signals for damage detection. The model's performance is optimized through automated hyperparameter tuning, ensuring robust and reliable damage classification. This innovative approach offers a promising solution for structural health monitoring, enabling early damage detection and more practical maintenance planning.
