| Abstract | ||
| The addition of steel fibers in reinforced concrete improves the toughness and the tensile strength of the obtained steel fiber reinforced concrete (SFRC). The latter property enhances the shear strength and the torque moment capacity of SFRC which mainly depend on the tensile strength. The current study is targeted towards developing an expression that is based on the thin walled tube (space truss) analogy adopted by American concrete Institute (ACI). In the proposed expression, the effective tensile strength of concrete in pure torsion in addition to parameters that are in accordance with thin walled tube (space truss) analogy are introduced as independent input parameters. Literature survey is carried out to collect experimental data pertinent to the torsional strength of SFRC beams. Based on regression analysis a new mathematical relationship that predicts the torsional moment for fiber reinforced concrete is derived. | ||
