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.

- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
- The design ratio of the cross-section check is different for the RF‑/STEEL and RF‑/STEEL EC3 add-on module. What is the reason?
- What is the meaning of the warning message ER061) Minimum amplifier of design loads <1?
- How can I optimize the calculation time in CRANEWAY?
- I would like to define lateral supports along the axis of a structural component that sometimes act on the upper flange, sometimes on the lower flange. However, it is only possible to select one item for each member. How can I create the entry?
- Is it possible to divide a free surface load by the existing lines in RFEM?
- I design a cross-section created in the SHAPE‑THIN program by using the design 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?
- In RF‑/STEEL EC3, I get an error message saying that the node with a support does not exist in the set of members. What is the reason?
- How do I display some results of all load cases in the printout report, but other results of the selected load cases only?
- Is it also possible to subsequently deactivate the symbols for the FE mesh refinement in an existing graphic in a printout report?
