Abstract: To increase the flexural capacity of reinforced concrete beams (RCC) beams, use of fiber reinforced composites bonded to the surface of RC members, started in the mid-1980s, has gained momentum due to limitations of plate bonding technique. Experiments were conducted to study the effect of 4-layerd symmetric cross-ply (SCP) GFRP laminates on the flexural behavior of simple RCC beams. It is observed that beam strengthened with the symmetric cross-ply laminate is suitable for enhancement of strength and stiffness of structural elements for restoration and retrofitting. The experimental results are also validated by the finite element based results using ANSYS.
