Seismic Analysis of Cylindrical Liquid Storage Tank

Abstract Liquid storage tanks are used in industries for storing chemicals,petroleum products,and for storing water public water distribution systems.Behaviour of Cylindrical liquid storage tanks under earthquake loads has been studied as per Draft code Part II of IS 1893:2002.Saddle and Lug Supported Tanks and Vessels - V Kupka,1994Besides local stresses the effect of buckling is not negligible.The difference between the loose and welded support is discussed.Unstiffened and ring-stiffened circular cylindrical tanks are taken into consideration.Derived formulae enable the designer to take into account the effect of cyclic loadSTRUCTURE magazine Earthquake Damage to Cylindrical API,Welded Steel Tanks for Oil Storage (API 650),American Petroleum Institute,2012.G.C.Manos and R.W.Clough,Further study of the earthquake response of a broad cylindrical liquid-storage tank model (UCB/EERC-82/07),Earthquake Engineering Research Center,University of
