Abstract

Fibre-reinforced plastic (FRP) composites are extensively used to retrofit civil structures. However, thequality and the characteristics of the bond between the FRP and the structure are critical to ensure theefficacy of the retrofit. For this reason, effective non-destructive evaluation (NDE) methods are oftennecessary to assess the bonding conditions. This article presents an ultrasonic technique for detectingdefects at the FRP-substrate interface. The technique uses the Akaike Information Criterion, to detectautomatically the onset of the ultrasonic signals, and the novel Equivalent Time Lenght (ETL) parameter, toquantify the energy of the propagating ultrasonic signals along the interface between FRP and concrete. Theuniqueness of the ETL is that it is not affected by the coupling conditions between the ultrasonic probes andthe structure. The proposed NDE technique has been tested numerically by performing 2D Finite-Elementanalysis and experimentally on reinforced concrete samples. The results show that the method is robustand cost-effective.
