An automated procedure for determining warping and torsional stresses in open steel members was developed by Joseph Palacak, Jr. in 1985. His FORTRAN program, called TORSION, determined stresses in wide flange, channel, and single angle members under various longitudinal bending and torsional loadings. In order to validate the TORSION program, twelve test cases were run and compared to the same cases analyzed using a commonly used manual technique. For this manual technique, the Torsional Analysis Case Charts, developed by Bethlehem Steel were used to compute warping and torsional stresses. Tables comparing the calculated stresses by the TORSION program and the torsion tables were developed. In addition, stress values from the hand-calculated problems were compared to values from GTSTRUDL output. Comparison tables between GTSTRUDL and the hand-calculated values are also presented.
