kamel27 Posted August 30, 2008 Report Share Posted August 30, 2008 salut les amis, j'ai eu un débat avec un collègue concernant le dimensionnement des poutres: lorsque on fait un prédimensionnement d'une poutre par exemple on prend H comprise entre L/15 et L/10 (soit L=13m par exemple H=120cm) si après modélisation j'ai calculé les contraintes et la flèche et je trouve que que ça vérifi avec H=80cm esq je peu prendre H=80cm meme si H est inférieure à L/15 ?? (en faite c une poutre qui supporte que son poid propre et avec H=80cm la flèche et les contraintes sont vérifié) merci d'avance ......
