The corrosion of steel reinforcement in concrete reduces the life of structures, causes high repair costs and can endanger the structural integrity of the structure itself. Glass fibre reinforced polymer (GFRP) offers a number of advantages over steel especially when used in marine and other salt laden environments. GFRP reinforcing bars are gradually finding wider acceptance as a replacement for conventional steel reinforcement as it offers a number of advantages. Technical studies on a number of concrete structures, from five to eight years old and constructed with GFRP reinforcement, have shown that there is no degradation of the GFRP from the alkaline environment. Concrete is very strong in compression but it is extremely weak in tension. To resist the tensile stress, steel reinforcement is provided in concrete. Reinforcement corrosion and structural deterioration in reinforced concrete structures are common, and prompted many researchers to seek alternative materials and rehabilitation techniques. One such material that has been offered as an alternative to mild steel reinforcement is Glass Fibre Reinforced Polymer (GFRP) bars and flats. For the repair and strengthening of structural concrete members, strengthening with Glass Fibre Reinforced Polymer (GFRP) plates is an excellent option. The present work is to study the behavior of Shear resistance of the silica coated GFRP stirrups in the shear test zone. A series of studies were conducted using silica coated GFRP stirrups in shear zone. It is observed that beams with silica coated GFRP flats shear reinforcement have shown failure at higher loads than the theoretical failure loads. Further it is observed that GFRP flats as shear reinforcement exhibit fairly good ductility.
