Question
For the foundation design, I need the results (support reactions) of the design situation for "static equilibrium". How do I get them?
Answer:
You can generate the load combinations of RFEM or RSTAB required for the static equilibrium design situation (EQU) according to EN 1990.If you activate the option to create combinations automatically, four design situations (ULS, S Ch, S Fr, and S Qp) are available. However, you can create a new additional action combination and specify a design situation for it (for example, EQU according to EN 1990).
With this specification, you obtain additional load and result combinations for the "static equilibrium" design situation, which you can then use for the design in RF‑/FOUNDATION Pro.

The three types of moment frames (Ordinary, Intermediate, Special) are available in the Steel Design add-on of RFEM 6. The seismic design result according to AISC 341-22 is categorized into two sections: member requirements and connection requirements.
The fatigue design according to EN 1992-1-1 must be performed for the structural components subjected to large stress ranges and/or many load changes. In this case, the design checks for the concrete and the reinforcement are performed separately. There are two alternative design methods available.
To evaluate whether it is also necessary to consider the second-order analysis in a dynamic calculation, the sensitivity coefficient of interstory drift θ is provided in EN 1998‑1, Sections 2.2.2 and 4.4.2.2. It can be calculated and analyzed using RFEM 6 and RSTAB 9.
The Steel Design add-on in RFEM 6 now offers the ability to perform seismic design according to AISC 341-16 and AISC 341-22. Five types of seismic force-resisting systems (SFRS) are currently available.
In the Concrete Design add-on for RFEM 6, you can perform the fire design of reinforced concrete slabs and walls according to the simplified table method (EN 1992‑1‑2, Section 5.4.2 and Tables 5.8 and 5.9).
When generating shear walls and deep beams, you can assign not only surfaces and cells, but also members.
In the Concrete Design add-on, you have the option to define an existing vertically oriented punching shear reinforcement. This is then taken into account in the punching shear design.
Do you have individual column sections and angled wall geometries, and need punching shear design for them?
No problem. In RFEM 6, you can perform punching shear design not only for rectangular and circular sections, but for any cross-section shape.
