Question
The design ratio of the cross-section check is different for the RF‑/STEEL and RF‑/STEEL EC3 add-on modules. What is the reason?
Question
In the RF‑/STEEL add-on module, I am trying to design a cross-section created in SHAPE‑MASSIVE. However, the cross-section is classified as invalid. What is the reason?
Question
For a buckling analysis, PLATE‑BUCKLING determines the governing shear stress of τ = 7.45 kN/cm², while RF‑/STEEL gives the result of the maximum shear stress of τ = 8.20 kN/cm². Where does this difference come from?
Question
What are the StandardID and AnnexID of various National Annexes for processing using the COM interface?
Question
How can I display the stresses in the stress points in RF‑STEEL Members?
Question
I am comparing the flexural buckling design according to the equivalent member method and the internal forces according to the linear static analysis with the stress calculation according to the second-order analysis, including imperfections. The differences are very large. What could be the reason for this?

Question
I have modified cross-section properties or reduced stiffnesses of a member in RFEM/RSTAB. After a new calculation, the deformation of the structural system has adjusted itself to the new cross-section properties. However, this change is not taken into account when performing design in add-on modules.
Question
When performing a design with STEEL, I would like to browse through the designed load cases to see the different stress distributions.How can I do this?
Question
Why do I obtain much higher design ratios in RF‑/STEEL than for cross-section design in RF‑/STEEL EC3?
Question
Which modules can be accessed via the COM interfaces RS‑COM and RF‑COM?
Stress Points
Where can I see the stresses in RSTAB 8?
Question
For a cross-section from the cross-section library of RFEM/RSTAB, the stresses calculated with RF‑/STEEL differ from the stresses of the same cross-section calculated with SHAPE‑THIN. What is the reason?
Question
When calculating a result combination, why does RF‑/STEEL not determine the same maximum internal forces as in the results within the result combination itself?
Question
Why do I get different results when calculating the stresses of flat, square, or octagonal steel, compared to the manual calculation?
The results deviate considerably, particularly in the case of shear stresses due to shear force and torsion.
Question
I used double members for the member input. Do I have to consider anything else, or is it better to enter a member with double cross-section properties?
Question
In RFEM/RSTAB, I use cross-sections with the values defined by direct input. How do I get the RF‑/STEEL add-on module to consider my cross-sections?
