attempt to carry too high a bolt force on a single attachment could result in tearing of the tank wall.Also,a fairly massive foundation may be required,especially for a larger tank.Thus,anchoring a tank is expensive,and,as a result,many tanks are unanchored,even in seismic areas.This is especially true for large capacity,broad tanks [1].SEISMIC RESPONSE OF SOIL-SUPPORTEDSEISMIC RESPONSE OF SOIL-SUPPORTED UNANCHORED LIQUID-STORAGE TANKS By Praveen K.Malhotra,' Member,ASCE the uplifting force at the end of each beam computed next centage of W,R.where WI = -rrR2p is the total weight of the liquid.For the results shown,the base plate thickness h =ON THE SEISMIC BEHAVIOUR AND DESIGN OF LIQUIDliquid storage tanks are considered and their seismic response is simulated numerically (a) A moderately-broad tank,referred to as Tank I,is primarily considered.This is a 27.4-meter-diameter tank with a total height of 16.5 meters.The tank is unanchored.The filling height of the tank H is equal to 15.7,which makes an aspect ratio of the

The inferred R (in the 1978 code) varies whether or not the tank is anchored or unanchored.This is a direct result of the 2.5 (unanchored) and 2.0 (anchored) multipliers that the 1978 code authors used,which was geared to penalize unanchored tanks (i.e.,require a higher base shear force for design).Once we convert the 1978 base shearLiquid Depth/Level to Hydrostatic Pressure CalculatorRelated ToolsUser GuideHelp1.Hydrostatic pressure to liquid level calculator 2.Local gravity calculator 3.Pressure units converter 4.Length units converterSee more on sensorsoneSome results are removed in response to a notice of local law requirement.For more information,please see here.12345NextImperfection-sensitivity of unanchored aboveground open A numerical analysis is conducted on several unanchored aboveground,open-top,steel,welded,liquid-containing storage tanks with imperfections subjected to seismic forces.Nonlinear material properties,nonlinear geometry deformations,and a flexible soil foundation idealized by a series of elastic springs are employed in order to simulate as-built field conditions of the tank at the time of Internal Design Pressure for Small Diameter API650 Tank I am reviewing the internal design pressures for the bulk storage tanks in our network and have stumbled across an issue with small diameter tanks.A conservative approach is being taken and the minimum allowable strake thicknesses (as per API653 4.3.3.1) are being used for the shell mass and area resisting compression in the shell to roof joint.
