| Popis: | These days, the most popular method for enhancing the flexural, shear and torsional properties of concrete is steel fiber reinforced concrete (SFRC). This study examines the torsional behavior of steel-fiber reinforced concrete beams in pure torsion. Fiber ratio, fiber type and concrete strength were factors in this study. To cast the tested beams, six different concrete mixtures were chosen. The first group (1) consists of three rectangular beams split into a control beam with a compressive strength of 20 MPa and two rectangular beams with various steel fiber ratios and types. The second group (2) is made up of three beams, with one rectangular beam serving as a control beam with a compressive strength of 40 MPa and the other two rectangular beams having various steel fiber ratios and types. All beams were cast and put through a strict torsion test. The objective of research is to study the crack pattern, crack torque, ultimate torque, torsion rigidity. The experimental study found that adding steel fibers to RC beams improved the ultimate torsion strength and decreased the angle of twist for beams when compared to control beams at the same load. Keywords: Steel fiber, reinforced concrete beams, torsional strength, angle of twist.
