B.karim Posted April 16, 2010 Report Share Posted April 16, 2010 bonsoir tout le monde ; voila j'ai rencontrer un probléme avec la condition de l'effort normal réduit voila la condition: 7.1.3.3 Effort normal réduit On entend par effort normal réduit, le rapport : v= Nd /Bc . Fcj Où Nd désigne l'effort normal de calcul s'exerçant sur une section de béton ; Bc est l'aire (section brute) de cette dernière fcj est la résistance caractéristique du béton 7.4.3.1 Sollicitations normales Outre les vérifications prescrites par le C.B.A et dans le but d'éviter ou limiter le risque de rupture fragile sous sollicitations d'ensemble dues au séisme, l'effort normal de compression de calcul est limité par la condition suivante : v<=0.3 sous sollicitations d'ensemble dues au séisme, veut dire qu'on prend la combinaison G+Q+E ou bien sous E et merci 1 Quote Link to comment Share on other sites More sharing options...
