Flexural and shear strength of reinforced concrete beams can be effectively increased by bonding a composite plate to the tension face or web of the beam. The plate undergoes tensile stresses and resists opening of the cracks. In this paper, experimental and analytical study of concrete beams strengthened with epoxy bonded fiber composite plate or fabric is reviewed. Guidelines and equations are also presented for flexural strengthening of concrete beams. Different modes of failure such as compression crushing of concrete, rupture of the plate and local shear failure have been considered in the development of the guidelines. The effect of web-bonded composite plate on the shear strength of the concrete beam is also discussed.
