Abstract

This chapter explores the enhancement of vibration-based failure identification in beam structures through the integration of statistical features and machine learning. The study introduces a novel statistically-based modal curvature index (SBMCI) for accurate damage localization, which outperforms traditional methods like the Modal Curvature Method (MCM) and the Mode Shape Curvature Squares Method (MSCS) by reducing false positives. The research also presents a hybrid approach combining the artificial hummingbird algorithm (AHA) with artificial neural networks (ANN) for precise damage quantification, even under noisy conditions. Case studies involving a simply supported steel beam and a three-span continuous concrete girder demonstrate the effectiveness of the proposed methods. The results show that the SBMCI index improves damage localization accuracy, while the AHA-ANN model achieves high precision in damage quantification with errors under 2%. This comprehensive approach offers a robust solution for structural health monitoring, making it a valuable resource for professionals in the field.
