Warping Torsion – Theory, Application, and Implementation in Structural Engineering Software

In elastostatics, torsion stresses are usually evaluated according to St. Venant's torsion theory. In this case, a circular beam cross-section is considered, wherein the cross-section remains planar despite the occurrence of rotation. In practice, however, thin-walled cross-sections are usually subjected to torsion, especially in steel construction.

In addition to the pure rotation, complex warping of the cross-section also occurs in the cross-section plane. If these warpings are restrained, warping stresses will result. To calculate these warping stresses, St. Venant's torsion theory was extended to the warping torsion theory. The objective of this thesis is to present the warping torsion theory in a clear and understandable way in order to manually calculate simple structural systems and to compare the results with the modeling and implementation in commercial structural analysis software.
