Abstract:The objective of this study was to examine the torsional behavior of reinforced fibrous concrete beams under pure torsion, and to develop a theoretical approach to analyze these beams. The addition of steel fibers to the concrete mix has been receiving more attention as a way of improving the properties of the concrete. This study has two objectives: 1) to observe the behavior of fibrous reinforced concrete in torsion, and 2) to present a realistic method for analysis of fibrous reinforced concrete in torsion. Nine beams were analyzed and experimentally tested. There were two beams with no fibers, seven of them with different percentages of fibers by volume (two different types). All beams had the same longitudinal bars but the hoop spacing was varied.
