Using bore-epoxy anchorage to delay debonding of CFRP plates strengthened concrete beams
Repairing of deteriorating structures has been done using different methods and techniques. Shear strengthening of Reinforced Concrete (RC) elements with externally bonded carbon fiber reinforced polymer (CFRP) plates and sheets have been widely used and accepted. It has been observed that de-bonding of the CFRP laminate and other strengthening materials is the most common type of failure. To address this issue many anchorage systems and methods have been developed. In this paper the use of bore-epoxy anchorage (Boring) system has been investigated. A total of five shear deficient RC beams were strengthened with carbon (CFRP) plates using bore-epoxy anchorage with bores of different diameters. The specimens were tested under four points bending. The results showed that the bore-epoxy anchorage delayed the CFRP de-bonding considerably and increased the shear capacity of the tested specimens by up to 48 % compared to the control beam.
