Abstract:The use of steel fibers as shear reinforcement in reinforced concrete beams is very promising. In this paper, an optimized high strength concrete with steel fibers (100 kg/m3) is used in rectangular beams (2.3 times .25 times .125 m), reinforced with longitudinal bars. This solution is compared with classical reinforced concrete. Five specimens are tested in four-point bending. The 28-day mean compressive strength of concrete is 90 Mpa measured on cylinders. The global behavior of the equal for all tested beams but the cracking is equal for all tested beams but the crack opening is smaller with steel fibers. No problems were encountered concerning ductility.
