Nowadays, many buildings and infrastructures are made of concrete and therefore, strength of concrete structural members ensures longer useful life and serviceability of the structure. Beams are one of the most important structural members that must have sufficient load bearing and ductility. Since brittle behavior and low ductility are two noticeable drawbacks of concrete members, they should
be reinforced by materials with higher ductility and tensile strength such as steel fibers which can significantly improve these two characteristics of bending members. With this respect, use of industrial steel fiber deposits, percentage of fibers and optimized amount of fibers are critical factors which affect the flexural strength of beams and cost–effectiveness of the projects. In this paper, experimental results of 3–point bending tests carried out on fiber reinforced concrete beams with different percentage of fibers are presented and compared and also its cost–effectiveness has been considered.<\div>
