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 corner with a docked beam, stiffeners, and any number of bolt rows?
- 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?
- I get the message "Torsion available -> no stability analysis possible". Why does this appear and what can I do?
Why are my steel members not being designed for stability in RF-STEEL AISC?
- My section is classified as Class 4 and non-designable in RF-/STEEL CSA. However, my manual calculation shows a different class. Why the difference?
- I have defined temperature loads, strain loads, or a precamber. As soon as I modify stiffnesses, the deformations are no longer plausible.
