A unified approach for determining the strength of Frc members subjected to torsion—Part I: Experimental investigation

The strength and behavior of fiber reinforced concrete (FRC) members subjected to torsion has received little attention in the literature. primary objective including fibers is bridge cracks once they form, doing so, provide some post-cracking resistance otherwise brittle concrete. This accompanying paper that follows present results a comprehensive experimental analytical study aimed at describing FRC torsion. In this paper, are presented on large scale pure tests which have been conducted eighteen 2.7 m long by 0.3 wide high beams with varying transverse longitudinal reinforcement ratios along steel types dosages. demonstrates addition significantly increases stiffness, rigidity maximum resisting torque twist when compared same specimen without fibers. substantially reduced crack widths spacings induced complementary specimens containing stirrups explored critical discussion low amounts conventional and/or reinforcement.
