maya GC Posted July 5, 2013 Report Share Posted July 5, 2013 bonsoir, j’espère que vous allez bien, 4.b Système de contreventement de structures en portiques par des voiles en béton armé. Dans ce cas les voiles reprennent au plus 20% des sollicitations dues aux charges verticales et la totalité des sollicitations dues aux charges horizontales On considère que les portiques ne reprennent que les charges verticales. Toutefois, en zone sismique III, il y a lieu de vérifier les portiques sous un effort horizontal représentant 25% de l’effort horizontal global Avec ce système de contreventement les bâtiments sont limités en hauteur à 10 niveaux ou 33 m au maximum. est ce que quelqu'un peut m'expliquer avec beaucoup de détail tous ce qui concerne ce système? quelle est la valeur de ksi à prendre? est ce que on vérifier les portiques seulement à 25% de l'effort horizontal, comment ça se fait? MERCI ! Quote Link to comment Share on other sites More sharing options...
