State-of-the-art review on FRP strengthened steel structures

Abstract: The use of FRP (Fibre Reinforced Polymer) to strengthen steel structures has become an attractive option which may produce confident retrofitting of existing structures. This paper reviews the following areas that have received only small coverage in previous review articles, but have developed rapidly: the bond between steel and FRP, the strengthening of steel hollow section members, and fatigue crack propagation in the FRP–Steel system. Future research topics have also been identified, such as the as bond–slip relationship, the stability of CFRP strengthened steel members, and fatigue crack propagation modeling.
