Abstract: Steel fiber reinforced concrete is a composite material that can improve the elastic behavior of reinforced concrete members. To understand the effect of SFRC on modulus of elasticity, torsional rigidity, the article attempts to present experimental study of steel fiber reinforced concrete (SFRC) beam subjected to pure torsion with different orientations of steel fibers. Hooked end steel fibers having aspect ratio 80 and use of fibers 1.5 % by weight of concrete is found to be optimal constituent. The study reveals that torsion strength enhances with addition of steel fibers in concrete .The randomly oriented fibers within limits of optimal volume fraction are observed to be imparting better torsion strength than orthotropic and transversely isotropic oriented SFRC beam. This property can be useful for improving the long term performance of the structure.
