The Torsional Warping (7 DOF) add-on offers you a wide range of new options. For example, you can perform the calculation of member structures in RFEM and RSTAB, taking into account the cross-section warping. You can consider the resulting internal forces (N, Vu, Vv, Mt,pri, Mt,sec, Mu, Mv, Mω) in the equivalent stress analysis of the steel design. Please note: This feature is currently not available for the design standards AISC 360‑16 and GB 50017.
