This paper presents the results of experimental study conducted to examine the effectiveness of steel fibre in enhancing flexural capacity of high strength concrete (HSC) beams. In this study a total of twelve beams of 3 m length and 150mm x 250mm in cross-section were cast and tested in the laboratory. One beam served as control beam (without fibre), three beams were casted with different fibre volume fraction.  Different grade of concrete (M60, M70 and M80) and different steel fibre volume fractions (0.5%, 1.0% & 1.5%) were the principal parameters considered in this study. All the beams were tested under four-point bending in a loading frame of capacity 750kN. Deflections were measured through appropriate instrumentations. The results showed that steel fibre reinforced concrete (SFRC) beams with 1% fibre volume fraction exhibit an increased strength, sufficient ductility, toughness and composite action until failure.
