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.

For reasons of result evaluation, clearly arranged result tables are available. The first window shows the maximum design ratios including the corresponding design of each designed load case, load combination, or result combination.
The other result windows list all detailed results sorted by specific subject in extendable tree menus. All intermediate results along the members can be displayed at any location. In this way, you can easily retrace how the module has performed the individual designs.
The complete module data are part of the RFEM/RSTAB printout report. You can select the report contents and extent specifically for the individual designs. The graphical result display of the governing design criteria in RFEM/RSTAB provides a quick overview of the design ratios of individual structural components.
It is necessary to enter material, load, and combination data in RFEM/RSTAB in compliance with the design concept specified by SIA 263.
The RFEM/RSTAB material library already contains the relevant materials for SIA. Furthermore, RFEM/RSTAB automatically creates the corresponding load combinations according to SIA 260. However, you can also create all the combinations manually in RFEM/RSTAB.
The RF-/STEEL SIA add-on module requires members and sets of members, as well as load cases, load combinations, and result combinations to be designed. In the next steps, you can adjust the preset definitions of lateral intermediate supports and effective lengths.
In the case of continuous members, it is possible to define individual support conditions and eccentricities of each intermediate node of single members. A special FEA tool then determines the critical loads and moments required for the stability analysis in these situations.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
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?
