Abstract

Fiber-reinforced polymer (FRP) composites are the modern,trustworthy alternatives to steel tendons and rebars. The bulk of currentresearch is devoted to establishing the feasibility of incorporating carbonfibre-reinforced polymer (CFRP) into reinforced concrete girders byevaluating the strength and reliability of CFRP and concrete components.In order to improve fatigue and corrosion resistance, CFRPs are crucial.Comparing reinforced prestressed concrete bridge girders strengthenedwith conventional steel reinforcement to those reinforced with CFRPs offersthe possibility of greatly increasing service life. Also widely researchedand used in bridge engineering as a corrosion-resistant substitute for steelreinforcement is CFRP composite material. The use of carbon fiber-reinforcedplastic (CFRP) reinforcement for prestressing concrete girders is a practicalsolution to the deterioration of concrete structures caused by corrosion ofsteel reinforcements. Serviceability demands may act as the determiningdesign factor for members that have been pre-stressed or strengthenedusing fiber-reinforced polymers. Given that CFRP reinforcement has a lowelastic modulus and a modest strain at failure compared to fully prestressedbuildings, partial prestressing may be the optimum method for increasingdeformability and reducing the cost of concrete structures.
