Abstract. The experimental study provides a series of tests for characterizing the structural behavior of fibre reinforced concrete beams subjected to shear loads. The paper involves usage of 2 types of fibers – polypropylene and steel fiber. The work suggests that the shear cracking resistance of the materials used are significantly improved by the fibers. The fibers reduced the crack width to about one quarter of the width in the shear-reinforced girders. Reliance on steel fibres increases the ductility of concrete. Adding steel fibres to concrete improves its post-tensile cracking behaviour. Shear strength is increased with the increase in fiber aspect ratio and fiber volume fraction. The concrete beams are casted for the size of 150 mm x 250 mm x 2100 mm. The behavior of fiber reinforced concrete beams for the addition of 0.4 percentage of fibers in both PFRC and SFRC under loading condition were observed and the load carrying capacity was increased compared to reinforced concrete.
