| Abstract: | Studies on the torsional behaviour of reinforced concrete members in general and fiber reinforced members in particular are of interest to several researchers as torsional rigidity, torsional stiffness and torsional toughness of the members play a vital role in the analysis of structures subjected to Seismic loads and Wind loads. In the present paper an investigation of the behaviour of steel fiber reinforced concrete members having single type of reinforcement, viz., longitudinal reinforcement or transverse reinforcement, has been presented. Torsion tests on 10 reinforced SFRC members revealed that single type of reinforcement, either longitudinal or hoop reinforcement, can not improve the torsional strength of the member beyond the torsional strength of the plain member without any reinforcement. However, single type reinforcement improved the ductility of the member. Steel fibers improved the cracking torque of the members noticeably. |
