Question:
In RF‑/STEEL EC3, is the "Elastic design (also for Class 1 and Class 2 cross-sections)" option under "Details → Ultimate Limit State" considered for a stability analysis when activated?
Answer:
Yes, if you activate the stability analysis in the "Stability" tab as well as the "Elastic design (also for Class 1 and Class 2 cross-sections)" option in the "Ultimate Limit State" tab (see image), the stability analyses are also performed with elastic cross-section properties.
