For the selection, the load reference is crucial. When entering the torsional moment, the load acts independently of the deformation. In detail, this means that the load remains constant when rotating the member around its axis. The more common case of dividing the load by the rotation is created using the defined eccentricity. For example, if there is an eccentricity for a load in the local z‑direction, the member torsion causes the resulting torsional moment to be partially redistributed in the local y‑direction, so the torsional moment failure is smaller than in the first case.

Shear walls and deep beams of a building model are available as independent objects in the design add-ons. This allows for faster filtering of the objects in results, as well as better documentation in the printout report.
The building story generator in the Building Model add-on allows you to automatically create building stories, depending on the topology of the model.
In the Concrete Design provides an option to perform seismic design according to AISC 341-16 for steel members.
Five SFRS types (Seismic Force-Resisting Systems) are available for this.
The combination wizard provides you with the option to consider more than one initial state. RFEM and RSTAB allow you to specify different initial states (prestress, form-finding, strain, and so on) for the target combinations in the combinatorics.
You can thus, for example, generate load states on the basis of a form-finding analysis with varying imperfections.
