A member's boundary conditions decisively influence the elastic critical moment for lateral-torsional buckling Mcr. In the program, a planar member model with four degrees of freedom is created for its determination. The corresponding coefficients kz and kw can be adjusted to represent frequently used cases. In this way, it is possible to describe the degrees of freedom arising from the support conditions at the member ends to be taken into account in the stability analysis for lateral-torsional buckling.

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.
