Bonjour a tous,

 

J'ai lancé analyse modale d'une Bâtiment de l'hôpital, j'ai essayé avec 250 modes. A la fin de démarche, Il a un avertissement, quelqu'un pourrait me dire, c'est quoi la faute et la solution, SVP.
Merci par avance.

I'm sorry but the picture is too small to read the warning. Assuming it is for a single missing eigenvalue than for seismic / spectral analysis just ignore it. The mass contribution for this mode comparing to 250 others that should produce over  90% of participating masses is insignificant.

This is exactly the situation I described. If you running seismic analysis just ignore the warning and check if you have over 90% of participating masses in the horizontal directions.
