A study on failure model and mechanism of SFRC torsion member

Based on the torsional tests to steel fiber concrete structures of different fiber volume fraction, this article did an analysis of the effect to failure model samples with different volume of steel fiber, and explored the incorporation of the torsion mechanism in the failure steel fiber. The tests results showed that: The incorporation of the steel of fiber significantly improved the mechanical properties of the steel fiber concrete, and it can reinforce limits of the torsion component cracking and ultimate torque.
