Abstract

Test results are presented for 26 rectangular eccentrically pretensioned concrete beams subjected to various combinations of torsion, bending, and shear. To investigate the effect of the presence of  stirrups, 18 beams were provided with closed rectangular stirrups and 8 contained no stirrups. Other variables investigated were the average level of prestress, the stirrup spacing, the T/(Vb) ratio, and the T/M ratio. Torque-shear and torque-moment interaction equations are proposed for both beams without stirrups and beams with stirrups.
