Unequal Flange I Beam Torsion (open section, non-uniform thickness)

Here an open section with non-uniform thickness and non-continuous median lines is analyzed to determine the maximum permissible torque it may withstand, applying a factor of safety. Under this torque, the angle of twist per unit length is found, as well as the absolute angle of twist and torsional springrate, assuming the length of the member is known. These analytical steps were applied to a standard unequal flange I beam cross-section that was looked up out of tabular data.
