Those tanks that are continuously supported with a flat bottom are typically larger storage and fermentation tanks,and are called flat bottom tanks.The flat bottom tanks are also anchored to concrete slabs.Damage to these tanks observed after the 2010 Maule Earthquake included anchorage failure and buckling of the stainless steel tank wall.STEEL VERTICAL CYLINDRICAL STORAGE TANKS -Jan 01,1973 self anchored flat bottom tanks Allowable Stress for Tests#0183;When welding the tank bottom,the welding sequence should be selected in such a See detail in f i g u r e 115 Section B-B S m a l l tank Largetank Bottom a n n u l a r plate Figure 11.6.Tank bottom layout manner that the shrinkage is kept to a minimum.Figure 11.6 shows the layout of bottom plates for a large and a small tank.Performance of Steel Tanks in Chile 2010 and 1985finery,all damaged tanks were self-anchored with fixed and floating roof.Observed fails in twelve at-mospheric tanks were principally elephant foot (BS),only in one case it was detected crack in joint bot-tom shell with lost of contain.All tanks were self-anchored,and possibly this cause an increment of stress in shell for uplift of wall.
