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)?
Effective Lengths for Steel Stability Design
How do I define effective lengths when designing steel members in RFEM 6?
Question
How can I create a curved or arched section?
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
How can I determine loads at particular geographic coordinates in the online service "Snow Load, Wind Speed, and Seismic Load Maps"?
Question
How are the location-specific Geo-Zone Tool data queries calculated for the determination of various building loads?
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?
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?
Overstrength Factors
How do I include the overstrength factor(s) Ωo in the ASCE 7 load combinations?
Question
Why is the load value displayed in the online service "Geo-Zone Tool: Snow Load, Wind Speed, and Seismic Load Maps" different from the value in the corresponding standard in some cases?
Splice Connection
How do I create a splice connection in the Steel Joints add-on?
Redundancy Factors
How do I include the redundancy factor(s) ρ in the ASCE 7 load combinations?
Exclude Lateral Torsional Buckling Check
My beam has a continuous lateral support and therefore lateral torsional buckling (LTB) is not a concern. How do I define the effective length?
Question
I need to define different types of lateral intermediate restrains for a single element in RF-/STEEL EC3. Is this possible?
Question
Is it possible to perform design for a timber-concrete composite cross-section?
AISI Table B4.1-1 Applicability Limits
Does RFEM check the applicability limits of AISI Table B4.1‑1?
Standardized Sections for AISI Design
Which standardized sections are valid for AISI cold-formed steel design in RFEM 6?
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
