Shear Behaviour of Concrete Wall Panels Reinforced with FRP Bars

Abstract

The use of Fiber reinforced bars as reinforcement in concrete structures are gaining more importance due to their advantage of being lightweight, anti-corrosion and easy to handle in construction works. This work is about the study on shear behaviour of concrete panels reinforced with FRP bars in the form a grid. Nine concrete panel specimens were cast with three varying spacing of Fiber Reinforced Plastics (FRP) reinforcements of 45 mm, 90 mm and 150 mm and also with three varying grades of concrete M20, M30 and M40. Strain measurements were observed in FRP bars and in concrete. The panels were loaded diagonally until it reached the ultimate strength and were made to fail ultimately. The crack patterns observed shows the behaviour of these panels under diagonal shear conditions. The results show that the composite panels reinforced with FRP bars were effective in carrying out the diagonal shear load and there was an increase in its capacity for an effective spacing and higher grade of concrete.KeywordsCompositeConcreteDiagonal shearFiber reinforced polymerShear wall panels
