Question
Does RF-/JOINTS Steel – Rigid allow to design a joint for the simultaneous action of an axial force and a moment for a beam-to-column connection?Answer
In RF-/JOINTS Steel - Rigid, the design is implemented according to EN 1993‑1‑8, Section 6.2.7, Equation 6.24. If the design axial force exceeds 5% of the plastic resistance Npl, Rd, Equation 6.24 applies.Keywords

This technical article analyzes the effects of the connection stiffness on the determination of internal forces as well as the design of connections using the example of a two-story, double-spanned steel frame.
SHAPE-THIN | Cold-Formed Sections
SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.

- Is it possible to use one of the RFEM/RSTAB add-on modules to design a frame joint with a docked beam, stiffeners, and any number of bolt rows?
- It is not possible to calculate the connection that I have created. Error No. 30863 appears. What should I do?
- I would like to connect a column rigidly to a girder flange. However, in the RF‑/JOINTS Steel - Rigid add-on module, beams are always connected to a column flange. How can I create a continuous beam?
- Does RF-/JOINTS Steel – Rigid allow to design a joint for the simultaneous action of an axial force and a moment for a beam-to-column connection?
- I have designed a steel connection using RF‑JOINTS and then created a model to compare it in RFEM. Why are the results not identical?
- How do I create a frame joint with taper in JOINTS Steel - Rigid?
- Why do I obtain different results for the same end plate joint in RF‑/JOINTS Steel - DSTV and RF‑/JOINTS Steel - Rigid?
- Why do I get large differences for the design of a longitudinally stiffened buckling panel in comparison with the German and Austrian National Annex?
- How can I perform the stability analysis in RF‑/STEEL EC3 for a flat bar supported on edges, such as 100/5? Although the cross-section is rotated by 90° in RFEM/RSTAB, it is displayed as lying flat in RF‑/STEEL EC3.
- How are the signs for the release results of a line release and line hinges interpreted?
