One consequence is that (for empty tanks) uplift of the bottom can be expected to occur more frequently than predicted using API 650.However,uplift does not necessarily mean bottom failure.Instead,the relative strength of the shell-to-bottom and roof-to-shell joints will determine failure.This ratio is larger for larger tanks.Fatigue evaluation of the API specification 12F shop Jan 01,2017 flat bottom oil storage tanks lap welded bottom joints#0183;Moreover,for tanks with 11 ft.(3.4 m) diameter or smaller,the allowable number of pressure cycles was dictated from the behavior of the shell-to-bottom joints instead of the roof-to-shell joints as recommended by the API 937 for storage tanks with frangible roof joint.It is also important to note that the inside evaluation points reflected Failure pressure and fatigue analysis of the API 12F shop Apr 20,2016 flat bottom oil storage tanks lap welded bottom joints#0183;welded flat-bottom tanks for oilfield production liquids.Moreover,this investigation aims to perform a fatigue analysis to estimate the minimum number of pressure cycles for each API 12F storage tank.The scope of the study included (a) an elastic stress analysis to determine the yielding the API 12F shop-welded flat bottom tanks.
