LEO10 Posted November 7, 2011 Report Share Posted November 7, 2011 Bonjour, Je dois dimensionner un poteau en tube circulaire hauteur 10 m supportant un panneau 1.60 m ht x 7.00 m largeur poids panneau 350 kg Doit on vérifier le phénomène d'oscillation forcée par le vent sur la structure en calculant la période propre, avec quelles valeurs de fréquences doit on comparer les résultats. Avez vous une méthode ? Peut on éviter ce calcul en limitant la flèche en tête due au vent normal ? Merci Quote Link to comment Share on other sites More sharing options...
