WebNov 25, 2003 · PXC (Structural) 15 Nov 03 07:35. Torsion is tough. There are 2 torsional constants which in general are both relevant: Pure torsion J which is dominant for closed sections, and warping torsion which governs for I beams. If you have access to FEA, a simple answer is to model the beam with plate elements. This is ideal for warping torsion.
