nico1881 Posted May 17, 2010 Report Share Posted May 17, 2010 (edited) Bonjour, Afin de réaliser un parking souterrain, il est nécessaire de réaliser un cuvelage avec revêtement d'imperméabilisation (cristallisation). La contrainte dans l'acier est donc limitée aux ELS (poussée hydrostatique). Cependant dans le DTU 14.1 il est nécessaire de vérifier la contrainte de traction du béton du coté du revêtement tout en sachant qu'elle est limitée (étant donné qu'en section "homogénéisée" on néglige le béton tendu). Comment la calculer ? j'ai fais un calcul mais j'aurais besoin d'avis. je calcul en section homogène avec : Uploaded with ImageShack.us Et ainsi je compare à la contrainte de traction limite qui est de 2,4 Mpa il me semble (C30). merci Edited May 17, 2010 by nico1881 Quote Link to comment Share on other sites More sharing options...
