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.

Frequently Asked Questions (FAQ)
- Why do I obtain different results for the same end plate joint in RF‑/JOINTS Steel - DSTV and RF‑/JOINTS Steel - Rigid?
- When modeling a beam connection to a continuous column, I have the problem that the column flange fails to bend. If I now add shims to the FRAME & # 8209; JOINT Pro add-on module, nothing changes at all design ratios. Why is that?
- How is the buckling load determined in RSBUCK if the most unfavorable value is transferred from RSTAB in the case of a non-constant axial force distribution?
- How does RF-STABILITY or RSBUCK determine the buckling load? According to the manual calculation, the respective buckling loads should be about 10% higher.
- I would expect the results from my load combination (CO) set to a linear analysis to equal the summation of the results from my load cases (LC) also set to a linear analysis. Why do the results not match?
- I would like to design an aluminum or lightweight structure. Is it possible to use RFEM or RSTAB for this?
- How can I set the deformation coefficient kdef in the program?
- I cannot find any reason why no plastic design is performed for a class 1 cross-section. Normally, you have to select the check box for the elastic design.
- A rigid member should only be able to absorb tensile forces or only compressive forces. What are the options for considering these nonlinearities in the calculation?
- Which Dlubal programs do I need to calculate membrane and textile structures?
