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)?

How do I define effective lengths when designing steel members in RFEM 6?
Question
How are the signs for the release results of a line release and line hinges interpreted?

How can I display membrane stresses in the results of RF‑STEEL Surfaces?
AISC 360-16 Shear Plane in Thread Option
Can I exclude bolt threads from the shear planes according to AISC 360-16 in the Steel Joints Add-on?
Question
Is it possible to perform automatic live load reduction in RFEM or RSTAB per the ASCE, IBC, or NBCC?
Question
RF‑STEEL AISC add-module shows non-designable results for general cross-sections because of shear buckling checks according to Chapter G. How do I solve this?
Overstrength Factors
How do I include the overstrength factor(s) Ωo in the ASCE 7 load combinations?
Question
After running the design in RF‑STEEL AISC, I receive error message 1002 - Invalid cross-section of type "Channel" according to F2. What does this error mean?
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?
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
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?
Question
Is it possible to integrate several sections with different materials in the flexural buckling analysis, or how can I apply several sections together?
Line Hinges on Several Surfaces
How can I efficiently define line hinges on several surfaces?
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
I designed a steel connection using RF‑JOINTS, then created a model to compare it in RFEM. Why are the results not identical?
Question
Does RF‑STEEL AISC perform torsion design per Design Guide No. 9?
Question
Which result combinations can I design with the RF‑/JOINTS Pro program, and what should I pay attention to?
Question
When designing seismic equivalent loads with a Response Spectra Analysis (RSA) in RFEM, how can I apply the modal response parameters Ie/R according to Sect. 12.9.1.2 in the ASCE‑7‑16 to my results?
