    Abstract

    Externally-bonded Fibre-Reinforced Polymer (FRP) reinforcement has been widely used around the world in the strengthening of Reinforced Concrete (RC) structures due to its various advantages, such as high strength-to-weight ratios, superior resistance to environmental attacks, and ease for installation. The bond behaviour between the FRPreinforcement and the substrate concrete plays a critical role in these structures as debonding of the FRPreinforcement is one of the main failure modes. Although extensive research has been conducted on such structures over the past two decades, reliable numerical simulation of debonding failures has only become possible in recent years. This paper presents a review of the key challenges in the numerical simulation of debonding failures in FRP-strengthened RCstructures and the recent progress in tackling these challenges; it also outlines research needs in the area. Aspecial emphasis is placed on the appropriate use of dynamic solution methods in capturing the complex debonding failure process.
