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.

- What is the purpose of a fillet weld in SHAPE‑THIN?
- Is it possible to model cold-formed sections in SHAPE‑THIN 8 and to design them in RF‑/STEEL Cold-Formed Sections?
- When calculating a cross-section, I get a message saying that the weld is not connected to two elements. 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 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 stiffened panel, I get the message that the boundary c/t-zone of the panel is not supported. 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?
- How does the calculation of the moments of inertia differ when the cross-section consists of several unconnected or connected partial cross-sections?
