| Abstract | ||
| This paper investigates the effect of steel and polypropylene fibers on static behavior of simply supported deep beams of normal concrete strength under patch loading. Also the paper studied the effect of web opening and its positions on shear capacity and mode of failures for steel fiber concrete deep beams under the same conditions of loading and strength. Sixteen beams of (1000*300*100mm), eighteen cubes (150*150*150mm) and thirty cylinders (150*300mm) in dimensions were cast with different fiber volume content (0, 0.4, 0.64 and 0.89%) as additives. Shear capacity, mode of failure and three of mechanical strengths were tested. After testing, the results indicate that shear capacity increases with increasing volume of steel fiber content with change on mode of failure while midspan displacement decreases. | ||
