rNowadays, by the expansion of the use of software in civil engineering science, it is possible to analyze and design more complex structures. By the increase of the complexity of structures, structural members sustain more sizable torsional moments. One of the methods for the strengthening of concrete members for torsion is the application of fiber reinforced concrete (FRC). In this study, fiber reinforced concrete beams have been investigated experimentally and using finite element software, ATENA, numerically.Steel fibers acquired from the recycling of spoiled tires have been utilized in this research. For the sake of the determination of FRC's post-cracking behavior, notched three-point bending tests have been performed. In addition, samples suitable for torsional loading of fiber reinforced concrete cross sections have been produced and examined. With the assistance of inverse analysis method regarding the results of three-point bending tests, the post-cracking behavior of FRC has been determined and employed in numerical modeling. Obtained results demonstrate considerable increase in deformability and energy absorption capacity of the torsional beams and also a negligible improvement of ultimate torsional strength of the membe
