The results are presented from an analytical study of wide-flange beams loaded with flexural and torsional loads. Of primary interest has been the determination of maximum design loads, including the interaction effects. The case considered was a wide-flange section with end moments and a central torque. It is suggested that the induced moment about the axis perpendicular to the axis of flexural loading be considered in determining the maximum normal stress for design. Design provisions are given.
