Concrete is a composite material which consists of cement, aggregates and some other alternatives such as steel reinforcements, fly ash, fibers, etc. In a structural member, torsion is usually associated with bending moments and shear forces. In this study, the influence of fluctuations in volumetric dosages of steel fibers on torsional rigidity has studied. Also the torsional moment of the concrete beam and the angle of twist is evaluated. Fibers are most generally discontinuous, randomly distributed throughout the concrete matrices. Fibers having the aspect ratio of 60 with different volumetric ratios of 9% to 13% with the weight of concrete have been used for this investigation. The specimens were casted as slender beams with cement and fine aggregate in the ratio of 1:1. The test results shows that the volume fraction of 12% having linear changes in the torsion with respect to the angle of twist.
