Abstract

This paper presents the investigation on severe damaged-RC beams repaired with epoxy injection and retrofitted with carbon fibre reinforced polymer (CFRP) on the soffit subjected to monotonic loading concurrent with acoustic emission (AE) monitoring. Ten beams were prepared namely reference beam (S1C) and damaged RC beam repaired with epoxy injection and strengthened with CFRP (S3B). The load, signal strength, average frequency-RA value and crack modes were analysed and discussed. As a result, the S3B produced highest maximum load and AE signal strength compared to S1C. In a nutshell, the AE can be used to identify the integrity of the damaged-RC beam repaired with epoxy injection and retrofitted with CFRP.
