Abstract

The use of externally bonded fiber reinforced polymer (FRP) reinforcement to strengthen reinforced concrete (RC) structures is becoming popular due to their superior properties such as, high tensile strength, long-term durability, corrosion resistance and light weight. The major issue in FRP is bond action between fiber reinforced polymers (FRP) and reinforced concrete members which affects the performance and reliability of external strengthening systems. Hence the study mainly focuses on the behavior of the interface between FRP and concrete. The behavior is examined through finite element (FE) simulations. FE simulation models were created for the parametric study to investigate the effect of several parameters on the bond behavior between FRP and concrete surfaces. The parametric study is conducted for different concrete grades by varying width and thickness of FRP laminate. The regression analysis is carried out and the best fit is arrived for the considered parameters.
