I am performing an analysis according to General Method 6.3.4 EN 1993‑1‑1 and have activated the addition "Adapted Method According to Naumes". The critical factor α*crit is displayed in red. Should I be worried?
The design is not successfully accomplished in RF‑/STEEL or in RF‑/STEEL EC3. RF /STEEL EC3 displays the warning "Maximum allowable thickness of material exceeded". What should I do?
Are the boundary conditions transferred from RFEM/RSTAB when performing the analysis with RF‑/STEEL Warping Torsion or with the General Method in RF‑/STEEL EC3?
I am designing a single-symmetric cross-section (T‑section) and get the message "Non-designable: ER056) The General Method is applicable only for I‑sections." Why?
What does the design information mean: Geometry error left side: End plate of the girder: Lambda2 >1.4 Column flange: Lambda2 >1.4 I cannot find an explanation in the manual or online.
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?
