Experimental Investigation of Compound Effect of Flexural and Torsion on Fiber-Reinforced Concrete Beams

Fiber-reinforced concrete is widely acknowledged for its ability to resist cracking effectively and limit propagation. By preventing cracks from spreading, the addition of fiber composites can enhance extensibility tensile strength, not only at initial point but also maximum capacity. Additionally, fibers in fiber-reinforced are capable binding matrix, even when exposed significant cracking. However, there limited information available about behavior under a bending moment combined with torsion. This study aims investigate structural members subjected torsion ratio equal 1. Synthetic steel 1.0% content different lengths (19, 35, 55 mm synthetic 13 straight hook fibers) were mixed mixtures examine effects types on beam performance. Test results indicated that beams showed higher moments than normal-strength beam. The hooked configuration reinforced increased capacity total torsional toughness length exhibited highest first-crack ultimate values among other tested beams. test compared past research models compound effect we modified these another factor represented influence capacity, as suggested research. comparison between predicted model presented good correlation.
