US6085472A - Method of protecting liquid storage tanks

A method of protecting liquid storage tanks from earthquakes and an anchor especially adapted to carry out this method are described.The method includes providing an energy dissipating anchor between the liquid tank and structure which will move with the ground.The anchor includes a stainless steel shaft which is secured to a ring foundation.Types of Joints in Concrete Water Tank Structures and Construction joints . Spacing between joints of water tank structures . the temperature changes to be accommodated are abnormal or occur more frequently than usual as in the case of storage of warm liquids or in uninsulated roof slabs,a smaller spacing than 30m should be adopted that is greater proportion of movement joints should be Steel Water Storage Tanks - Home American WaterJames E.Noren,P.E.Advance Tank and Construction Company (Chap.6 Construction of Welded-Steel Water-Storage Tanks) Steven P.Roetter,P.E.Tank Industry Consultants (Chap.8 Inspecting New-Tank Construction) Jeffrey Rog Corrpro (Chap.3 Controlling Corrosion) Sami F.Sarrouh,P.E.Brown and Caldwell (Chap.9 Operation)

ABSTRACT The analysis of the behavior of ground supported cylindrical steel liquid storage tanks under seismic load requires consideration of a number of complex factors.Seismic Analysis of Liquid-Storage Tanks - The ConstructorDec 27,2011 partially anchored liquid storage tanks construction#0183;Large-capacity ground-supported cylindrical tanks are used to store a variety of liquids,e.g.water for drinking and fire fighting,petroleum,chemicals,and liquefied natural gas.Satisfactory performance of tanks during strong ground shaking is crucial for modern facilities.Tanks that were inadequately designed or detailed have suffered extensive damage during pastSECTION Fuel Systems - FEMA.govFigure 3.2.3C An underground fuel tank anchored to a concrete counterweight Courtesy of Adamson Global Technology Corp.Figure 3.2.3D An underground fuel tank anchored onto poured-in-place concrete counterweights Underground Storage Tank (UST) use should be minimized due to environmental con-cerns.

Preventing Tank Flotation PetrolPlaza

Anchor 12 foot diameter tanks if the water level could be expected to reach the bottom of the tank. Keep in mind that the size of the excavation may need adjustment.The worst case scenario occurs when the tank must be restrained while it contains little or no product,and the water level in the excavation reaches finished grade.Preventing Flotation of Underground Storage TanksNov 26,2013 partially anchored liquid storage tanks construction#0183;The same concept applies to underground storage tanks.If the water table reaches a high level or if flood waters reach a high flood stage,the air in the tank will start to exert an upward force.Because of the large volume of underground storage tanks,this upward force can be very strong.Preventing Flotation of Underground Storage TanksNov 26,2013 partially anchored liquid storage tanks construction#0183;The same concept applies to underground storage tanks.If the water table reaches a high level or if flood waters reach a high flood stage,the air in the tank will start to exert an upward force.Because of the large volume of underground storage tanks,this upward force can be very strong.
