A large, U-shaped, thin-walled, reinforced concrete beam, restrained at both ends with heavy diaphragms, was subjected to torsional moment at midspan and tested throughout postcracking and post yielding ranges to its ultimate capacity. Measured strains in the longitudinal steel, and stirrups, and torque-angle of twist curves, torque at yielding and cracking were compared with predictions based on the theoretical models proposed by the writers in a companion paper. Very good agreement was obtained.
