In RF-/FOUNDATION Pro, the foundation design requires the definition the corresponding loading (load cases, load combinations, or result combinations) for the different design situations (STR, GEO, UPL or EQU).
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.

- SHAPE‑THIN calculates a very small shear area. Why?
- When calculating a connection with the FRAME JOINT Pro add -on module, a message appears saying that the value is outside the allowable range (prev. Value: 108, min. Value 100, max. Value 100). What does this message mean?
- I have a trapezoidal roof structure that is supported by beams. However, the moments on the beams are smaller than they should be. What could be the reason for this?
- Why are some load cases displayed in red in RF-STEEL EC3?
- Why are the equivalent member designs grayed out in the Stability tab when activating the plastic designs by using the partial internal force method (RF‑/STEEL Plasticity)?
- At which position are the determined support forces for the crane runway girder? At the bottom flange of the crane runway girder or in the shear center of the cross -section?
- How do I create a frame joint with taper in JOINTS Steel - Rigid?
My member is oriented at the inclination of principal axis when I import from SHAPE-THIN to a 2D RFEM model. How do I fix this?
- For cross-section design of a flat steel, I obtain abnormally high shear stresses due to the torsion in the STEEL EC3 add-on module, which can be disproved by a simple manual calculation. What is the error?
- When calculating a cable using the STEEL EC3 add‑on module, there is the error message "Incorrect characteristic stresses for material No. 1! Please correct this in Table 1.2."
