Bonjour,

 

Est ce que quelqu'un peut m'expliquer comment on calcul les coefficient de majoration sur appui ( et non sur ma travée ).

 

l'expression générale de la formule qui permet de  calculer le coefficient de majoration dynamique est :

 

ϒm = 1  +  0.4/ (1+0.2*L)  +  0.6/ (1+4*G/S)

 

L : Portée de la travée

G : charge permanentes 

S : Surcharge

 

Merci .
