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.

- Overall maximum response factors and critical nodes
- Resonant analysis (maximum response factor, RMS acceleration, critical node, critical frequency)
- Impulsive (transient) analysis (maximum response factor, peak acceleration/velocity, RMS acceleration/velocity, critical node, critical frequency)
- Vibration dose values for both resonant and impulsive analyses
- Response factor vs walking frequency
- Mass participation vs eigenmodes

- When calculating a longitudinally stiffened panel, I get a message saying that the stiffener cannot be at the end of the panel. What should I do?
- When calculating a buckling panel, I get a message saying that some elements are connected to the panel, but they are not defined as stiffeners. What should I do?
- When selecting the elements for a stiffener of a stiffened panel, I get a message saying that at least one of the selected elements is a null element. What should I do?
