Abstract:

In this paper, the predictions of the theoretical model and results obtained in the inspection of FRP wraps on concrete samples with seeded defects are presented. Additionally, the successful use of this NDE technique in the detection and imaging of delaminations, debonds, cracks and steel reinforcement in FRP-Concrete structures are discussed. These results are presented in the form of displayed RF waveforms and color-coded C-scan images. Finally, a description of a prototype inspection system for FRP-retrofitted concrete structures developed during the Phase II of the project is presented.
