smlboy90 Posted December 30, 2013 Report Share Posted December 30, 2013 Bonjour, Je suis entrain de faire un calcul d'un hangar métallique (comparaison entre calcul manuel et avec ROBOT) .Et j'ai utilisé des portiques hyperstatiques d'ordre 3 (aucune articulation entre poteau et traverse) et dans la vérification de la stabilité de la traverse contre le déversement, j'ai considérer la traverse comme bi-encastrée, ce qui donne des coefficients B et C inférieur à 1, par contre ROBOT prend la valeur 1 pour ces 2 coefficient dans ce cas. J'ai essayer de modéliser une poutre bi-encastrée dans une autre affaire pour voir l'impact sur les valeurs de ces 2 coefficients mais il les prends tjrs égal à 1. Et merci. 1 Quote Link to comment Share on other sites More sharing options...
