The calculation of a result combination in STEEL EC3 or ALUMINUM takes a very long time. What might be the cause, and how can I improve the performance?
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 determining the effective cross-section properties according to EN 1993‑1‑1, EN 1993‑1‑5, or EN 1999̩1‑1, SHAPE‑THIN displays a warning message saying that the effective widths are only determined for straight elements. What does this mean?
In an older model of RFEM 4 or RSTAB 7, I designed a SHAPE‑THIN cross-section or a general cross-section in STEEL EC3. At that time, cross-section Class 1 or 2 was determined. Now, I have opened the model in RFEM 5 and the cross-section is only classified as Class 3 or Class 4. Why? Was the design more cost-efficient at the time?
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?
For the current standards, it is highly time-consuming to take into account all relevant load situations and to select the governing situation for the design checks. Is there any easy way to do this?
