摘要: Abstract Torsion of structural members and the behavior steel fiber reinforced concrete became area interest many researchers in past it is still newsworthy. In this study, 12 (R/C) beams with Steel Fiber Reinforced Concrete (SFRC) were tested to observe failure under torsional moments. The volumetric content, aspect ratio, longitudinal reinforcement variables investigation. Unit angle twist versus moment (torque) response each specimen was monitored during experiments, effect above on critically investigated. It observed that not only torque capacity R/C beam modified by addition Reinforcement (SFR) but also energy absorption significantly affected SFR addition. Besides, an empirical equation relating for SFRC proposed against test data.
