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.

- Which Dlubal Software programs are required to calculate membrane and tensile structures?
- I would like to analyze cable and tensile structures. Is it possible to use RFEM or RSTAB for this?
- I compare 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 is the reason?
- In spite of having defined smooth ranges, they are not considered in the design in RF‑STEEL Surfaces. What setting have I missed here?
- When calculating a cable using the STEEL EC3 add‑on module, there is the error message "Incorrect characteristic stresses for material No. 1! Please correct this in Table 1.2."
- Are effective length factors determined automatically from a model in the add-on modules for the aluminum and steel design or do I have to make adjustments?
- I design a cross-section created in the SHAPE‑THIN program by using the RF‑STEEL EC3 add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General." What can I do?
Is it possible to calculate with American steel cross-sections?
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- How can I quickly model a chimney with reinforcement rings and stiffeners?
