ABSTRACT

Reinforced concrete (RC) structures are generally subjected to increasing loads, age-related deterioration and design changes that affect the integrity of structures. Therefore, this paper presents an experimental investigation of a carbon fibre reinforced polymer (CFRP) reinforced RC beam under three-point loading. Acoustic emission (AE) was used to monitor the progression of damage. The loading, AE intensity and AE signal strength were analysed and discussed. The analyses were performed using the AE signal collected from CH6 and CH7. The result is that crack nucleation produces high signal intensity compared to other crack modes. Moreover, the intensity plots fit the identified crack modes when the beams were reinforced with CFRP. Therefore, AE can be used to evaluate the performance of the CFRP reinforced RC beam.
