text: This means that the most interesting procedure , if it is desired to define a cross section with the exact geometry of the profiles (and not made of rectangular thin-walled elements) to use it in STATIK, for example, it will be done introducing a model of the cross section like in case 2.a), exposed before (cross section entered with a polygonal contour including a hole) and manually entering, in the indicated field on the previous figure, the value of the torsional stiffness from the Ix obtained with an auxiliary thin-walled model.
