New type of force
It is possible to compute a new type of force that is an analogue to the shear force for warping (model type 6). The lateral-torsional moment is calculated in the design cross-sections of bars; for this moment, the diagrams along the length of the bars are generated for FE 7. This type of force is required in order to compute the tangential stresses in the analysis of the load-bearing capacity of elements subject to torsion.
