First Steps with RFEM
Description
The RF-/STEEL EC3 add-on module can perform the design of fillet welds for all parametric, welded cross-sections of the cross-section library. For this, the option must be activated in the detail settings of the module. Alternatively, a surface model can also be used for the design.

Design of Neck Welds of Welded I-Sections and Box Sections
The RF‑/STEEL EC3 add-on module can perform the design of fillet welds for all parametric, welded cross-sections of the cross-section library.
- What is the meaning of the "Activate Weld Design" option in the detailed settings of RF‑/STEEL EC3?
- I am comparing the flexural buckling design according to the equivalent member method and the internal forces according to the linear static analysis with the stress calculation according to the second-order analysis, including imperfections. The differences are very large. What could be the reason for this?
- I cannot see any members if the RF‑/STEEL EC3 add-on module is selected as a "load case"; why?
- To which axes do the support rotations and support eccentricities in RF‑/STEEL EC3 Warping Torsion refer?
- What does the load application point in RF‑/STEEL EC3 Warping Torsion refer to?
- When designing a beam, I would like to neglect the torsion included in the stability analyses using the filters described in Knowledge Base article #001498.I define the filter, but the torsion warning appears at the same x‑location again. Do the design internal forces change, or why is that?

What are the options in RFEM or RSTAB for determining the ideal elastic critical moment for any cross-sections and systems/loads?
Is it also possible to design flat steel (brackets, flat steel stringers of staircases)? -
