Behaviour of Precast, Prestressed Y-Beams in Shear, in Torsion, and in Negative Bending

Five full-size Y-beams with cast-in-place flanges were tested in shear, torsion or negative bending. The results show satisfactory agreement with basic theoretical approaches to the prediction of web shear cracking resistance, uItimate shear strength, ultimate fIexura1 strength, and torsional stiffness.
