When performing design with PLATE‑BUCKLING, all design checks are fulfilled. Nevertheless, the critical load factor is smaller than 1. Ist der Nachweis nun erfüllt oder nicht?

Q: When performing design with PLATE&#8209;BUCKLING, all design checks are fulfilled. Nevertheless, the critical load factor is smaller than 1. Ist der Nachweis nun erfüllt oder nicht?

This phenomenon is entirely possible because the critical load factor is calculated without the influence of the plastic reserves – in other words, purely elastically.However, the buckling design according to EN 1993&#8209;1&#8209;5 activates the plastic reserves. The design is thus fulfilled.
