The RF-/STEEL EC3 add-on module automatically transfers the buckling line to be used for the flexural buckling analysis for a cross-section from the cross-section properties. In particular for general cross -sections, but also for special cases, the assignment of the buckling line can be adjusted manually in the module input.
SHAPE-THIN Table "6.2 Classification of the Cross-Section According to EN 1993-1" and Stress Diagram
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 necessary to enter the loads of a crane for each axle or wheel in the table of crane loads in Window 1.4?
- When doing a calculation, I activated the 'Detailed Calculation' option. Have the support loads already been specified with the reduced dynamic coefficient for dimensioning the substructure?
- What do the abbreviations for the crane loads in the CRANEWAY Add-on Module mean?
- 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 create a curved or arched section?
- How are the signs for the release results of a line release and line hinges interpreted?
- 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 hot-dip galvanized components considered for fire resistance in the RF‑/STEEL EC3 add-on module?
- How is the rotational stiffness of a buckling stiffener determined in PLATE‑BUCKLING?
- In RF-/STEEL EC3, is the "Elastic design (also for cross-section class 1 and 2)" option under "Details → Ultimate Limit State" considered for the stability analysis when activated?
