Abstract: Structural Health Monitoring (SHM) of civil structures using IoT sensors is a major emerging challenge. SHM aims to detect and identify any deviation from a reference condition, typically a damage-free baseline, to keep track of the relevant structural integrity. Machine Learning (ML) techniques have recently been employed to empower vibration-based SHM systems. Supervised ML can provide more information than unsupervised ML, but it requires human intervention to appropriately label data describing the nature of the damage. However, labelled data related to damage conditions of civil structures are often unavailable. To overcome this limitation, a key solution is a Digital Twin relying on physics-based numerical models to simulate the structural response in terms of the vibration recordings provided by IoT devices during the events of interest, such as wind or seismic excitations. This paper presents such comprehensive approach to address the damage localization task by exploiting a Convolutional Neural Network (CNN). Early experimental results related to a pilot application involving a sample structure, show the potential of the proposed approach and the reusability of the trained system in presence of varying loading scenarios.
