Towards the Use of Digital Image Correlation to Measure FRP-Concrete Debonding in Reinforced Concrete Structures
This paper presents a simple and cost-effective method to detect and measure debonding in reinforced concrete (RC) structures retrofitted with externally bonded fiber-reinforced polymer (FRP) sheets. Debonding is a phenomenon that occurs when the FRP sheet separates or delaminates from the concrete substrate. Digital image correlation has been used extensively in the past to measure displacement, strain, and crack fields over the surface of a structural element. In this study, a tool is developed in the freely-available image analysis software ImPro Stereo to allow for the measurement of the out-of-plane displacement field over the surface of a structural element. This tool is then applied to detect areas over the surface of a structural element where FRP-concrete debonding has occurred. Validation of the developed tool in ImPro Stereo in a controlled laboratory environment demonstrates that it provides a non-destructive, non-contact, and cost-effective solution to measure FRP-concrete debonding. The results show great potential for its application in structural condition assessment and structural health monitoring of civil structures.
