most efficient on-site method with a 22% increase in load-carrying capacity over other strengthening methods. AE health monitoring shows that damage to different components of the strengthened beam can be detected. AE Cumulative hits and CSS can differentiate different load phases, and a historical index can be used to monitor major events during loading. RA-AF classifies tensile to shear mode damages. This study proves that AE-based health monitoring can be successfully implemented to characterize, classify, and detect damage to different material components in an on-site strengthened RC beam. Also, irrespective of strengthening the methodology, AE parameters can detect damage.
