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.

- In RF-/STEEL EC3, I get an error message saying that the node with a support does not exist in the set of members. What is the reason?
- How do I display some results of all load cases in the printout report, but other results of the selected load cases only?
- Is it also possible to subsequently deactivate the symbols for the FE mesh refinement in an existing graphic in a printout report?
- What is the difference between SHAPE‑THIN 9 and SHAPE‑THIN 8?
- SHAPE‑THIN calculates a very small shear area. Why?
- When calculating a connection using the FRAME‑JOINT Pro add-on module, a message appears saying that the value is out of the valid range (existing value: 108, minimum value 100, maximum value 100). What does this message mean?
- I have a trapezoidal roof structure supported by beams. However, the moments on the beams are smaller than they should be. What could be the reason for this?
- How can I export the effective lengths from the RF‑STABILITY add-on module to Excel?
- In the RF‑/STEEL EC3 add-on module, I have selected two bracings with the same size as the shear panel type in the "Parameters" window for a beam to be designed. Thus, the beam should be supported laterally in the middle. Why is the eigenvector arbitrary anyhow?
- Why are some load cases displayed in red in RF‑STEEL EC3?
