The type of storage tanks normally encountered in refinery, petrochemical and other industrial plants have cylindrical shells, essentially flat bottoms, and either cone roofs or float roofs. Tank size may range from 10 to 200 feet in diameter with height from 16 to 56 feet. AFES Modules 2. Suggested conditions for Tank Foundation Type is as below. < Table 1 > Tank Foundation Type Earth Foundations with a Crushed stone Ringwall Conditions to be considered The subgrade has adequate bearing capacity and acceptable settlements When the anchorage is not necessary* Advantage The most economical type of tank foundation Provides uniform support of the tank bottom by dissipating concentrated loads in a granular pattern Possible the uneven settlement which cause additive effort in the future Difficult to construct flat level plane of the bottom of the shell of the tank (⇒ Leveling Ring※) Catastrophic failure of the bottom is possible if a leak starts and washes out the underlying support Large Diameter Tanks Disadvantage Application (Design Basis to be applied) 2/50 < Table 2 > Tank Foundation Type Earth Foundations with a Concrete Ringwall Conditions to be considered Large tanks, tanks with heavy or tall shells and self-supported roofs impose a substantial load on foundation under shell Can be used where high foundation uplift forced are encountered resulting form internal pressure or wind/seismic loading to provide for anchorage Allows very good leveling of the periphery of the bottom and the shell which is positioned on it Can used in congested areas with space Relatively high cost than the crushed stone ringwall foundation Small Diameter Tanks Reinforced Concrete Slab Advantage Disadvantage Application (Design Basis to be applied) < Table 3 > Tank Foundation Type Conditions to be considered Advantage Disadvantage Application (Design Basis to be applied) Pile supported foundation where soil bearing pressures are very low The reinforced concrete slab is very recommendable when the level of the underground water is high The foundation is very expensive All Tanks 3/50 Notes * Regions of low seismicity or in seismic areas where the tank diameter to height ratio is such that there is no uplift of the tank shell or small sloshing effect. The magnitude of lateral forces, overturning moments, and associated hydrodynamic mass be determined to assess their impact on tank shell and foundation design ※ A concrete leveling ring can be used under the tank shell in the gravel ring wall foundation. This leveling ring is 200mm deep by 300mm wide unreinforced concrete whose primary function is to provide a stable level base upon which the fabricator can build the tank shell wall. Additional advantages of the leveling ring are to distribute concentrated shell loads on to the gravel ring wall and minimize edge settlement under seismic condition 4/50 Tank Foundation Design Process Start Choose Project Create Structure Input Foundation Geometry (=Node Data) Assign Foundation Module (Foundation Type: Tank1 ) Input Feature Data (=Footing, Pier Shape, Dimension) Set Footing Bar, Pier Bar IF Pile Foundation, Array Pile Data Set Anchor Bolt/Box Input Equipment Data Input Load Case/Combination Structural Calculation sheets Take Off Bill of Materials Generate Construction Drawing Generate 3D Modeling Data END 5/50 Choose Project that you want to work on in “Project Dialog Window”.
