Seismic Analysis of Liquid-Storage Tanks

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 past earthquakes.Earthquake Seismic Analysis of Liquid-Storage TanksLarge-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 past earthquakes.Earthquake Second Revision No.50-NFPA 780-2015 [ Detail ]A ground ring electrode or ground loop conductor supplemented by grounding electrodes as identified in 4.13.2 through 4.13.7 shall be provided for structures containing flammable vapors,flammable gases,or liquids that can give off flammable vapors.7.3.7.2 A metal tank shall be grounded by one of the following methods:

Ring Beam - an overview ScienceDirect Topics

1.The shell of a column-supported tank,vessel,or bin is considered to be a circular girder or ring beam uniformly loaded over its periphery and supported by columns equally spaced on the ring circumference.2.The ring beam (girder) is subjected to compression,bending,and torsion due to the weight of the tank and contents and horizontal wind or seismic force.Reviews 446(PDF) Design of a Floating Roof Crude Oil Storage Tank of For the pontoon support leg,1leg/6m of tank circumference was appr oximated,and for the centre deck support leg,for tanks diameter up to 60m,1leg/34m ground supported tanks Compression Rings#178; of center deck area is approximated.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 []
