Concrete, a mixture of different aggregates bonded with cement, first developed around 150BC in Rome has been bedrock to the modern Infrastructure. It is used to build everything from roads, bridges, dams to sky scrapers. Strengthening concrete is traditionally done by using steels but the developments in technology in recent decades allowed to use fiber reinforced plastics which are externally bonded to concrete . Such composite materials offer high strength, low weight, corrosion resistance, high fatigue resistance, easy and rapid installation and minimal change in structural geometry. This study investigates the behavior of reinforced concrete beams bonded with fiber composites. A numerical study is conducted to study the behavior of RC beam under Static third point loading. Concrete beam specimens with dimensions of 150 mm width, 300 mm height, and 2600 mm length are modelled. These beams are externally bonded with Glass Fiber Reinforced Polymer (GFRP) sheets and Carbon Fibre Reinforced Polymer (CFRP) sheets. In present study, we examine the performance of reinforced concrete beams which are bonded with GFRP and CFRP sheets with various thicknesses (1, 2 & 3 mm) using ABAQUS in terms of failure modes, enhancement of load capacity, load-deflection analysis and flexural behaviour

The experimental study was carried out on the cyclic loading behaviors of impaired reinforced concrete beams strengthening with prestressed CFRP sheets. Eight beams in four groups with or without strengthening with prestressed CFRP sheets were tested, in which one or two layers of prestressed CFRP sheet were bonded on the bottom surface of the beams. Based on the analyses of test results, the flexural stiffness and ultimate resistance under cyclic load were effectively enhanced for the strengthened beams with the increasing layers of CFRP sheet, but the ductility of their mid-span deflection was reduced.
