Answer:
Cross-sections assigned to Class 1 or Class 2 are designed plastically in RF‑/STEEL EC3 by default. To be able to compare the results with RF‑/STEEL, please activate the elastic design of class 1 and class 2 cross-sections in the Details dialog box of RF‑/STEEL EC3 (Image 02).
Please also check whether the same partial safety factor γ for the resistances of the cross-sections is defined in both add-on modules (Image 03 and Image 04).
