Question Poids du réservoir


Recommended Posts

je prépare memoire R+9:angry:

COMMENT calcule Charges permanentes de reservoir

Calcul des surfaces " Saff" est :

 S=1.5x2.25=3.37 m²

 Charges permanentes :

 Poids du réservoir: G=(poids des deux dalles inferieure et supérieure/4 + poids des parois/2

 (5.1x0.15x25x1.85/2)+(3.6x25x0.15x1.85/2)+(0.15x5.1x3.6x25x2)/4=64.60 KN

 Poutres principales : Gpp = 0,30 x 0,40 x 25 x 4.8/2 = 7.2 KN

 Poutres secondaire : Gps = 0,30 x 0,30 x 25 x 3.3/2 = 3.71 KN

G =75.51 KN

 Surcharge d’exploitation =poids de l’eau+ surcharge d’entretien

Q =3.37x2x10+3.37x1 = 70.77 KN
