RF-/JOINTS Steel - Rigid | Design
In RF-/STEEL EC3, sets of members are calculated according to the General Method (EN 1993-1-1, Cl. 6.3.4) together with stability analysis. For this, it is necessary to determine the correct support conditions for the equivalent structure with four degrees of freedom.
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 difference between SHAPE‑THIN 9 and SHAPE‑THIN 8?
- When calculating a connection using the FRAME‑JOINT Pro add-on module, a message appears saying that the value is out of the valid range (existing value: 108, minimum value 100, maximum value 100). What does this message mean?
- How can I export the effective lengths from the RF‑STABILITY add-on module to Excel?
- In the RF‑/STEEL EC3 add-on module, I have selected two bracings with the same size as the shear panel type in the "Parameters" window for a beam to be designed. Thus, the beam should be supported laterally in the middle. Why is the eigenvector arbitrary anyhow?
- 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)?
- Where can I find 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?
- 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."
