Flexural, torsional, compressive and shear behavior of Steel Fiber Reinforced Concrete (SFRC) is already studied individually but none has studied the performance of SFRC beams under a combined effect of more than one state i.e. tension, flexure, torsion, compression and shear in general by now. In this study M20 grade of concrete beams under composite behavior of flexure, shear and torsion with different compositions of fibers mix were investigated. The dimensions of specimen beams was 100 mm x 100 mm x 500 mm and straight cylindrical fibers of length 0.28 mm and aspect ratio 100 were mixed. A total of 48 specimen were casted and tested such that for every percentage of fiber and each torsion value three beams were tested. Hence there are four torsion values 0, 61.75, 119.41 and 176.53 N-m are applied (4x3x4=48) It was found during study that ultimate bending stress and deflection increases due to increase in torsion where as the ductility reduced with the torsion enhancement for a specific fraction of fiber content.
