In Modern days fiber-reinforced polymer (FRP) composites are rigorously applied to strengthen reinforcedconcrete structures. FRP composites t proved to be very efficient in gaining higher strengths at structural memberlevel. However, the main issue regarding its use is that it detached from concrete surface. Most practiced methods forFRP-to-concrete applications had shown very positive results, those methods such as FRP U-jackets, Anchoring withFRP anchors, bolting metal plates on FRP composites sheets and mechanical anchoring fastener. The efficiency ofthose anchoring methods had been tested and equations regarding strains have been developed. Based on thosemodels, strength can be predicated for concrete members, however, strength of the structural system cannot be exactlypredicated as the actions in structural system become different during cyclic loading. New anchorage methods, needto be explored to prevent debonding in structural system rather than for single structural members.
