Presents the results of an analytical investigation into the experimental and ultimate strength capacity of I2 reinforced concrete right angle bents fixed at each end and subjected to a single concentrated load. Sixteen reinforced concrete beams having the same cross-sectional properties as the bents were also tested in flexure, torsion, and combined flexure and torsion to obtain the applicable interaction relation between the bending and twisting strengths of the section. The analytically computed collapse loads obtained on the basis of this interaction relationship and the experimental collapse loads of the bents are compared. Some design recommendations are suggested. .
