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 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.

Moment frame design according to AISC 341-16 is now possible in the Steel Design add-on of RFEM 6. The seismic design result is categorized into two sections: member requirements and connection requirements. This article covers the required strength of the connection. An example comparison of the results between RFEM and the AISC Seismic Design Manual [2] is presented.

The fatigue strength design is based on the analysis using damage equivalent factors. The damage equivalent stress ranges ΔσE,2 and ΔτE,2 related to 2*106 stress cycles have to be compared to the limit values of the fatigue strength ΔσC or ΔτC for 2*106 stress cycles of the corresponding detail, taking into account the partial safety factors.
In this way, the individual design requirements are specified. Separate design cases enable flexible analysis of selected members, sets of members, and actions, as well as of individual cross‑sections. Design-relevant parameters such as B. selecting the design concept as well as partial safety factors can be defined freely.
After the calculation, the module displays results in clearly arranged result tables. All intermediate values (for example, governing internal forces, adjustment factors, and so on) can be included in order to make the design more transparent. The results are sorted by load case, cross-section, set of members, and members.
If the analysis fails, the affected cross-sections can be modified in an optimization process. It is also possible to transfer the optimized cross-sections to RFEM/RSTAB for a new calculation.
The design ratio is represented with different colors in the RFEM/RSTAB model. This way, you can quickly recognize critical or oversized areas of the cross-section. Furthermore, result diagrams displayed on the member or set of members ensure targeted evaluation.
In addition to the input and result data, including design details displayed in tables, you can add all graphics into the printout report. This way, comprehensible and clearly arranged documentation is guaranteed. You can select the report contents and extent specifically for the individual designs.
After opening the add-on module, it is necessary to define designed members/sets of members, load cases, load or result combinations for the fatigue strength design.
The materials from RFEM/RSTAB are preset and can be adjusted in RF-/STEEL Fatigue Members. The material properties listed in the respective standard are included in the material library.
The design requires damage equivalent factors as well as detail categories on the designed stress points to be considered in the calculation.

How do I define a plastic hinge in RFEM 6?
How can I exchange data between RFEM 6 / RSTAB 9 and IDEA StatiCa?
How can I generate an area load on members via cells in RFEM 6 or RSTAB 9?
In the Steel Design add-on, I have set the boundary conditions in such a way that the I-beam flange is restrained against the horizontal displacement. I then calculated the critical load factors using the Structure Stability add-on, but with no effect on the critical load factor value. What is the reason for this?
Where can I find my customer number in RFEM or RSTAB?
How can I define temporary supports for a form-finding process in RFEM& 6?
