Test data are presented on the shear strength of a series of reinforced cement concrete (RCC) deep beams with three steel fiber volume fractions (0, 1.0 and 1.25%), three shear span to-effective depth ratios (0.75, 1.0 and 1.25) and three combinations of web reinforcement. A total of 18 beams were tested to failure under two-point top loading. The test results indicate that the fibers have significant influence on the shear strength of a longitudinally reinforced concrete beams. Shear strength increases with increasing fiber volume and decreasing shear span to-effective depth ratio. Steel fibers can replace the conventional web reinforcement in RCC deep beams.
