It is known that steel fiber-reinforced concrete (SFRC) members have enhanced torsional performances, compared to typical reinforced concrete members, but, our understanding on torsional behavior of SFRC members are yet very limited due to insufficient research on this topic. Thus, this study performed torsional tests on SFRC members, in which radial strain gradients developed in thin-walled concrete tube were measured in detail. The shortcomings of current design codes on the torsional strength of heavily reinforced members in transverse direction have been also discussed. Test results showed that the SFRC specimens having larger volume fraction of steel fibers had greater torsional strength and more ductile behavior as well. The compressive strains in the extreme fiber of SFRC members were estimated at about 0.0035 to 0.0040 at ultimate state. All specimens had the initial cracking angle of about 45 degrees, while the inclined angles at ultimate became somewhat smaller. The current code provisions overestimated the torsional strengths of all specimens that were over-reinforced against torsion.
