GSE Steel software – Torsion and warping

GSE Steel considers restrained warping for the torsion of thin-wall open sections. Notice that this phenomenon is not included in most commonly used frame analysis programs.

It is important to note that the torsional stiffness of an open section is function of the warping end conditions as well as the location of the torsional load. Thus, the distribution of the forces in a structure having members resisting torsion may differ whether the «Consider Warping due to Torsion» option is enabled or disabled.
