Data-Driven Damage Detection and Localization in a Truss Bridge Based on Series Analysis
摘要
In order to maintain the efficiency and safety of transportation networks, Ensuring the structural integrity of bridges is of utmost importance. This study presents a data-driven framework for detecting and localizing structural damage based on anomaly detection in the bridge’s structural responses. The methodology is applied to the Old ADA Bridge, represented by a Finite Element model refined through Bayesian updating via the Transitional Markov Chain Monte Carlo (TMCMC) technique. The interaction between passing vehicles and the bridge is characterized using a Vehicle-Bridge Interaction (VBI) model, facilitating a more accurate assessment of structural behavior. To detect and localize damage, the Matrix Profile technique is employed to identify anomalies in sensor-acquired signals. The proposed approach demonstrates a high degree of efficacy in detecting structural changes using a minimal dataset, thereby eliminating the need for prior supervised learning. This feature enhances its practical applicability, making it a viable tool for real-world bridge health monitoring.
