Deep beams are an important element in infrastructure and offshore structures. This paper investigates the shear capacity of glass fiber reinforced polymer GFRP reinforced high-strength fibrous concrete deep beam. (12) supported concrete deep beams with (GFRP) reinforcement have a cross-section of 150×340 mm under a one-point load and have been tested to fail. The test variables were the vertical web reinforcement ratio (0, 0.0025, 0.004, and 0.0053) and steel fiber volume fraction (0, 0.5, and 1%). All beams have a length of 1020mm, an effective span of 620mm, and an effective span-to-depth ratio of 1.02. The longitudinal reinforcement is 3D16 mm at the bottom and 2D6mm at the top. The test results analysis shows that the increase of vertical web reinforcement ratio from (0 to 0.0053) increases the failure load by (7.88 and 15.44) and decreases mid span deflection by (15.52 and 22.95) for fiber volume fraction (0 and 1%), respectively. Also, when the vertical web reinforcement ratio increases from (0 to 0.0053), the flexural crack increases by (20.02 and 29.50%) and the diagonal crack load by (38.5 and 51.15%) for fiber volume fraction (0 and 1%), respectively.
