After activating the warping torsion, you can perform a second calculation including a stability analysis, for example, with the first combination wizard. Torsional buckling is also taken into account. In the example of the stair tower, the governing stability failure has changed. Instead of a global failure, there is now a local failure of a single stringer. Since the minimum critical load factor (5.67) is less than 10, it is necessary to carry out a cross-section analysis for the stair stringers. This is described in this chapter.
