Answer:
Yes, it is. For the design of the relevant components, it is necessary to define them as sets of members and select them for the design.
Furthermore, it is important that no members are selected for design in the warping analysis design case that are either already included in the sets of members or are subjected to torsion, since the RF‑/STEEL EC3 add-on module would then design them by means of the equivalent member method and no design may be possible due to the torsion. A warning message would then appear.
