Experimental Investigation and Modeling of FRP–Concrete Joint Bond Strength Based on Failure Depth

The growing interest in fiber-reinforced polymer (FRP) composites in recent years for use in strengthening concrete structures bears witness to their efficiency and ease of use. A major issue in FRP strengthening designs, however, is the determination of the bond strength (ultimate load capacity) of the FRP strips, which is quite dependent on their debonding off the concrete substrate. Identification of the major parameters involved in the...
