Error: Attention! Not all combinations could be checked

In the details of the steel verification, you see the error:

Attention! Not all combinations could be checked

[NL]: Opgelet! Deze controle kon niet worden uitgevoerd voor alle combinaties of posities.

[FR]: Attention! Cette vérification ne pouvait pas être effectuée pour toutes les combinations ou positions

[ES]: Attención! No se han pdido verificar todas las combinaciones

 

Cause

There are 2 posible causes:

  • Some load combinations only cause axial force, no bending moment. Then there is not reason the verify combined forces.
  • Not all formula to do the steelcheck are lineair. Some have a limited reach.
    For example the check for ‘Bending + Axial force’ in hollow sections requires a ratio n = NEd/NRd to be calculated (EN 1993-1-1 §6.2.9). If n > 100, no result for the check ‘Bending + Axial force’ will be found.
