Self-Anchored vs.Mechanically-Anchored Storage Tanks

Mar 24,2009 Construction of self anchored flatbottom tanks#0183;The tank is self-anchored providing the following conditions are met The resisting force is adequate for tank stability (i.e.,the anchorage ratio,J1.54).The maximum width of annulus for determining the resisting force is 3.5% of the tank diameter.The shell compression satisfies E.6.2.2.Reinforced Concrete Water Tank Design RequirementsReinforced concrete water tanks are constructed for storing water.The design of reinforced concrete water tank is based on IS 3370 2009 (Parts I IV).The design depends on the location of tanks,i.e.overhead,on ground or underground water tanks.The tanks can be made in different shapes usually circular and rectangular shapes []Petroleum - Self Contained Above Ground Tanks forTank Capacity Self Contained Above Ground Tanks and 4.5 metres from building openings.Access to Tank Storage Area Access to the tank storage area must be restricted to authorized personnel only.Signs to this effect must be firmly anchored with bottom of guard rails at 600 mm above ground.

Design of Steel Tanks - The Constructor

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.DEVELOPMENT OF THE WORLDS LARGEST ABOVEdevelopment of the large capacity LNG storage tank is to reduce the construction cost and the boil-off gas and use the tank building site more effectively.The large tank was designed for the KOGAS Tongyoung and Pyeongtaek LNG Receiving Terminals.The design work was done through numerous structural,thermal and seismic analyses.DESIGN RECOMMENDATION FOR STORAGE TANKS ANDlarger tanks,and as such the seismic design for these larger storage tanks has become more as well as the Ds value of an anchored cylindrical steel-wall tank.As the number of smaller under-ground tanks used for the storage of water and fuel is increasing in Japan,the Sub-committee has added them in the scope of the recommendation
