TITLE :AN EXPERIMENTAL STUDY ON IMPROVEMENT OF RCC BEAM USING FRP COMPOSITES
Corrosion of steel in reinforced concrete structures is one of the biggest challenges faced by the civil construction industry today. In reinforced concrete structures, corrosion of steel reinforcement due to harsh environmental conditions considerably reduces the durability and life span of these structures. To overcome this corrosion problem, many new techniques have been tried and found to be either expensive or ineffective. Fiber Reinforced Polymer (FRP) materials in the form of solid bars has been successfully tried as a substitute for steel reinforcement in concrete structures. FRP materials are anti-corrosive, have low weight to strength ratio and are used for various modern engineering applications. After analysis of the experimental results, a design equation was formulated to predict the shear carrying capacity of GFRP web reinforced deep beams. The results obtained by using this equation were found to be acceptable and so, this equation may be adopted for predicting the shear load capacity of deep beams reinforced with GFRP web reinforcement and loaded within a small ‘shear span to depth ‘ratio.
