jeanpauld 11 Report post Posted April 14, 2014 Bonjour, Question n°1 Sur un batiment industriel considéré comme totalement fermé de dimensions 15x50x8ht le calcul du coefficient µ donnerait µ=0. Dans ce cas peut on simplement prendre cpi = +0.35 (l'abaque pour µ s'arrete à 0.33) ou doit on obligatoirement prendre deux cas ci-dessous ? cpi=+0.2 et cpi = -0.3 Question n°2 Le calcul de µ abouti normalement à une seule valeur de cpi par : pouvez vous me confirmer que c'est bien le cas ? Dans ce cas pourquoi utilise-t-on par defaut les cas de "surpression" et "depression" ? Merci de vos eclaircissements. A+ Quote Share this post Link to post Share on other sites
