Question
How do you perform a lateral-torsional buckling analysis for asymmetric steel cross-sections?
Elastic critical moment for lateral-torsional buckling
What are the options in RFEM 5 or RSTAB 8 for determining the ideal elastic critical moment for lateral-torsional buckling for any cross-sections and systems/loads? Is it also possible to design flat steel (brackets, flat steel stringers of staircases)?
Overstrength Factors
How do I include the overstrength factor(s) Ωo in the ASCE 7 load combinations?
Question
Is it possible to generate wind loads according to DIN EN 13782 with this program?
Question
What does the load application point in RF‑/STEEL EC3 Warping Torsion refer to?
Redundancy Factors
How do I include the redundancy factor(s) ρ in the ASCE 7 load combinations?
Question
When entering data in the RF‑/STEEL EC3 add-on module, I get the error message "Incorrect location of the intermediate lateral restraint". Why?
Question
What is the meaning of the abbreviations for the crane loads in the CRANEWAY add-on module?
Question
How can I optimize the calculation time in CRANEWAY?
Question
I am performing a stability analysis according to the second-order analysis. Why is the partial safety factor γM1 used for the stress analysis here?
Boundary Moments in Warping Torsion
I use RF-/STEEL Warping Torsion to design an eccentrically modeled wall beam, which is loaded transversely with a distributed load. While the bending moments in the main program are zero at the member start and member end due to the hinges, RF‑/STEEL Warping Torsion outputs moments there. Thus, the span moment is reduced incorrectly. How do I get the boundary moments to zero?
Question
How do I superimpose generated equivalent loads from the seismic analysis?

Question
Are the models and presentations from Info Day 2020 freely available, and can you send them to me?
Implausible Results – Torsional Warping
My results of the calculation with Torsional Warping are implausible. What could be the reason?
Custom Sections for AISI Design
Can I design user-defined (parametric) sections according to AISI S100 or CSA S136?

Question
How can I enter or read out a response spectrum via the COM interface in DYNAM Pro?
Question
Is it possible to process the input data, such as effective lengths of several members or continuous members, in the add-on modules RF‑/STEEL EC3, RF‑/STEEL AISC, or RF‑/STEEL CSA?
Question
Why it is not possible to design a biaxial bending with the RF‑/JOINTS add-on module?
Question
For a calculation, I activated the "Detailed Calculation" option. Have the support loads already been specified with the reduced dynamic coefficient for the design of the substructure?
Question
I cannot see any members if the RF‑/STEEL EC3 add-on module is selected as a "load case"; why?
Question
