Although all checks are OK in PLATE-BUCKLING, the critical load factor is less than 1.0.
Does this mean the design is satisfied or not?
This can happen, because the critical load factor is calculated without the influence of plastic reserves, that is, as purely elastic.
In the plate-buckling design according to EN 1993-1-5, the plastic reserves are mobilized.
This means that the design is satisfied after all.
