Apr 01,2006 ground supported liquid storage tanks Metal Considered to Have Reinforcing Value#0183;Tens of studies have been carried out and many special programs have been coded to analyze the fluidstructure and/or the soilstructure interactions for other liquid storage structures,such as ground-supported cylindrical tanks (Fischer et al.,1991; Zeiny,1995) and dams (Chavez and Fenves,1994; Tan and Chopra,1996).Seismic response of base isolated liquid storage ground tanksMar 01,2011 ground supported liquid storage tanks Metal Considered to Have Reinforcing Value#0183;The properties of the studied cylindrical broad and slender tanks are given in Table 1.The tank is considered as filled to a height H with water.For steel wall the modulus of elasticity is taken as E = 29000 Kips/in.2 and the unit weight, s = 0.49 Kips/ft 3.The liquid storage tank is represented by the mechanical system illustrated in Fig.1 for broad or slender tanks on the basis of the

A rectangular steel tank is shown in Fig.The rectangular steel tanks are made of steel plates with flat bottom.The widths of steel plates generally adopted are 1.20 m,1.25 m and 1.30 m depending upon availability of the plates.the thickness of steel plates should not be less than 6 mm.Cited by 14Publish Year 2011Author Ayman A.Seleemah,Mohamed El-SharkawyReinforced Concrete Water Tank Design RequirementsSep 27,2013 ground supported liquid storage tanks Metal Considered to Have Reinforcing Value#0183;9.Minimum reinforcement for RCC water tank.Minimum reinforcement required for 199mm thick sections is 0.3 % of the area of concrete section which reduced linearly to 0.2% for 450 mm thick sections.Moreover,in case of floor slab for tank resting on ground the minimum reinforcement from practical consideration should not be less than 0.3% of the gross sectional area of the floor slab.Bund Wall - an overview ScienceDirect TopicsThe way the tank failed was explored by placing parts of the base,sidewall and bund wall next to one another in a reconstruction of this crucial part of the tank where the failure started (Fig.4.33).It was immediately apparent that the tank wall was severely distorted outward,especially when the inner tank wall was compared with the flat and unaffected outer or bund wall.
