The computation of torsional stresses in rolled steel sections is not new. The application has been confined, however, to eccentric loads where the torque, or torsion moment, could be obtained by multiplying the load by the eccentricity. The case of hanger bolts suspended from a steel girder flange and supporting an intermediate stair landing might be cited as an example. A steel spandrel girder with a floor beam framed into its web presents a torsion problem of a different type. The deflecting floor beam twists the spandrel and a torque is introduced—the computation of which is analogous to that of the bending moment brought to a column by a rigidly connected beam. This torque has been neglected for the following reasons: (1) No simple method of computation has been advanced; and (2) it has not been considered of sufficient importance to justify an extended analysis.
