Abstract:
Test results of 26 semicontinuous reinforced concrete T-beams without web reinforcement under combined bending, shear, and torsion are reported. M/Vd ratios of 1.5, 3, and 6 were investigated, with the torsion segment 3d, 6d, and 12d long. All but four beams were over-reinforced to permit the primary study of shear and torsion interaction. The effect of torsional cross-sectional warping was investigated. Span length and cross-sectional warping were not found to influ-ence the behavior greatly. Torsion lowered beam shear strength much less than ordinary plastic theory would suggest.
