A small, powerful, versatile and straightforward software application will be introduced to analyze problems of warping torsion by means of the analogy between the straight beam-column under mixed transverse and axial loading and the straight beam under restrained warping. This software, originally developed to analyze multi-span beam-columns immersed on elastic foundations, resorts to a high order finite element. Validation against a number of already solved cases will be provided, including, but not limited to the cases in the AISC-Design Guide 9. Additionally, the present work will provide a brief account on the first order general torsion theory, a discussion on the roles analogies play in sciences and engineering, an account on the equivalent beam-column analogy as special case of the equivalent beam on elastic foundation, some details of the aforesaid high-order-finite element, and a contribution of a novel convergence study regarding the axial tensile parameter.
