Manual adjustment of the buckling curve according to EN 1993-1-1
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 | 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.

- Why do I get high differences when designing a longitudinally stiffened buckling panel compared to the German and Austrian National Annexes?
- How can I create a curved or curved section?
- How can I perform the stability analysis for an edgewise supported flat steel, for example 100/5, in RF-/STEEL EC3? Although the cross-section is rotated by 90 ° in RFEM/RSTAB, it is displayed lying flat in RF-/STEEL EC3.
- How are the signs to be interpreted for the release results of the line release and line hinges?
- How is the rotational stiffness of a buckling stiffener determined in FE-BUCKLING?
- How are hot -dip galvanized components considered for fire protection in the Steel EC 3 add -on module?
- 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?
- How can I get the member end forces to design the connections?
- I would like to calculate and design "temporary structures." What do I need for this?
