Question : Deplacements inter-étages

Recommended Posts

Salam, Une question posé par un ingénieur :

j'ai bâtiment en R+12, j'ai trouvé des déplacements inter-étages comme suit :

le coefficient de comportement R=5

le déplacement admissible inter-étage est de 3,2cm (hauteur d'étage 3,2m)

pour certains étages j'ai trouvé des déplacements très proches du déplacement admissible du reglement.

cela est acceptable?

Nota :

la première colonne montre les valeurs des déplacements inter-étage selon la direction principale X

la deuxième colonne montre les valeurs des déplacements inter-étage selon la direction principale Y

la troisième colonne se sont les déplacements inter-étage admissibles (3,20 cm correspond a 1% de la hauteur d'étage qui est de 3,2m)
