Experimental study of flexural behaviour of reinforced concrete plate strengthened with FRP laminates

Abstract

    The reinforced concrete structures are common in structural civil engineering, road and irrigation constructions. Load carrying capacity of the structures can be enhanced through the use of FRP laminates (fiber reinforced polymers) stuck on the tension surface of structures. Behaviour of the structures after strengthening is complicated due to the redistribution of internal forces by loading. The presence of the FRP laminates causes the changing of the failure states, especially damage may occur due to the debonding between concrete members and composite plates. Within this paper, the behavior of a reinforced concrete strengthened with composite plates are analyised through experimental methods. The achieved results will be analyzed and discussed.
