In recent years, fiber reinforced polymer(FRP) materials in form such as pultruded plates and fabrics have been attractive for use as strengthening materials for reinforced concrete members. Due to premature debonding of FRP strengthening materials accompanied by sudden and brittle failures, the field application of FRP strengthening material has been reduced. Newly Glass fiber-Steel plate composite Plate as a strengthening material has been developed. The thin steel plate in Glass fiber-Steel plate composite Plate makes usage of the anchoring system possible, which could delay or prevent the premature debonding failure. The beams strengthened with Glass fiber-Steel plate composite Plate showed greater strength as well as ductility than those strengthened with any other strengthening materials commercially available. In order to examine the effects of Glass fiber-Steel plate composite Plate on shear capacity of strengthened beam, systematic experimental investigations were performed for 3 control and 60 strengthened beams. The experimental results showed that shear capacity of strengthened beams with Glass fiber-Steel plate composite Plate considerably increased in shear capacity compared with the control ones.
