Removing Cross-Section from Design
I do not want to design a cross-section in the RF‑/STEEL EC3 add-on module. Can I quickly remove this cross-section from the selection?
Info Day Online 2018
Are the models and presentations from Info Day 2018 freely available, and can you send them to me?
RF-STEEL Surfaces - Membrane Stresses
How can I display membrane stresses in the results of RF‑STEEL Surfaces?
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?
Design of SHAPE-THIN Section
How can I design any SHAPE‑THIN cross-section in detail in RFEM 5 or RSTAB 8?
Question
How can I display the stresses in the stress points in RF‑STEEL Members?
Question
When trying to calculate the design in RF‑STEEL Surfaces, I receive Warning No. 1162 - Surface No. XX is of the type "Orthotropic" and cannot be designed. What does this warning mean?
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
In STEEL, it is possible to select the Sigma Delta stress in the details. What kind of stress is this?
Question
Is it possible to display a parts list of a specific cross-section using the STEEL add-on module?
Question
I have created new elements in my model. However, they are not being designed. What can I do?
Equivalent Stress
Why are there different equivalent stresses in RFEM 5 and RF‑STEEL, although the same CO is considered?

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
In spite of having defined smooth ranges, they are not considered in the design in RF‑STEEL Surfaces. Which setting did I overlook?
Buckling Analysis
How can I perform a buckling analysis for a surface in RFEM 5?
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?
Question
When performing plastic design, I get stresses displayed that exceed the yield criterion. Have I done anything wrong?
Question
Can I use the RF‑STEEL Surfaces add-on module to perform fire resistance design for steel surfaces?
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.
Steel Bracket
I have to dimension a wall bracket as a steel brackets that I have modeled as surface components in RFEM 5. Which add-on module can I use to design it?
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?
Question
I get a note that the surface will not be designed, because it is divided into several components. Why?
