Develop and validate a non-destructive structural health monitoring framework combining acoustic emissions and unsupervised machine learning to detect and classify localized corrosion within post-tensioned bridge anchorages.
Integrated acoustic emission (AE) sensing with k-means clustering initialized via k-means++ to partition high-velocity multi-parameter AE data streams across an n-dimensional Euclidean feature space.
Deployed the Identification of Active Anomalies (IAA) system on an operational cable-stayed bridge under real traffic loading to establish a benchmark acoustic signature database.
Corroborated algorithmic classification boundaries through physical forensic inspections, material sampling, and crack opening displacement measurements during structural rehabilitation.
Successfully identified and classified multi-mechanism structural deterioration, confirming active corrosion states within heavily confined anchorage blocks against physical forensic sampling.
Established quantitative correlations between extracted acoustic emission clusters and structural crack opening widths, enabling real-time differentiation between micro-corrosion, macro-defect propagation, and cable anchorage slippage.
