I would like to calculate a hall frame with loads from a crane runway. It is not quite clear to me what the various action categories denote. Can you explain it to me?
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)?
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?
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?
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?
