Preuplift Method to Anchor Liquid Storage Tanks

Steel tanks for liquid storage often consist of a cylindrical shell attached to a steel bottom plate which rests on the ground.In many cases neither the bottom plate nor the cylindrical shell are fixed to the ground.When such an unanchored tank is subjected to seismic ground shaking,the lateral inertia of the contained liquid contributes to People also askWhat is the minimum thickness of an above ground storage tank?What is the minimum thickness of an above ground storage tank?the minimum thicknesses of each part in above ground storage tank according to API 650 as followong - minimum thickness for first course in shell having inside diameter less than 60 m is 6 mm without corrosion allowance.- minimum thickness for annular plate of bottom plates is 10 mm with corrosion allowance.Minimum Thicknesses Of Above Ground Storage Tank Plates Life Management Of Above Ground Atmospheric StorageThe tanks were originally constructed with 1/4 inch (6mm) floor plate with no annular ring replacements incorporate a 10 mm thick annular ring.Cathodic protection can help but does not provide a complete answer,as soil conditions can be very difficult and small portions of
