Question

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.

Answer:
The auxiliary values λ1 and λ2 are required to determine the effective lengths.

These two values are used to determine the α value from Figure 6.19 of EN 1993‑1‑8, which is then used to calculate the effective lengths (for non-circular flow lines) of the T-stub flanges.
The maximum value for λ1 is 0.9 and the maximum value for λ2 is 1.4 → see Figure 6.11 of EN 1993‑1‑8.
Based on your geometry, however, a λ2 of >1.4 results for the end plate, for example.
α can only be calculated with the maximum value of 1.4.
