Abstract

Glassfi bre-reinforced polymer (GFRP) jackets were used in several different ways to improve the flexural and shear performance of reinforced concrete (RC) beams. The GFRP jacket increased both the ductility and the strength of the concrete beam. Anexperimental and analytical study was conducted to investigate the use of the GFRP channel in improving the flexural capacity of a RC wide beam. The parameters investigated in this study were stiffness, ductility and failure mode. The test results showed that using the GFRP channel signifi cantly improved the flexural capacity of the RC wide beams. The tensile stresses due to the inclined cracks in the concrete can be transferred to the concrete oneach side of the crack when interfacial bond activities are maintained.
