Appendix P of API 650 gives a method for determining the allowable external loads on tank shell openings.This method is based on papers by Billimoria and Hagstrom ``Stiffness Coefficients and Allowable Loads for Nozzles in Flat Bottom Storage Tanks`` (1977) and by Billimoria and Tam ``Experimental Investigation of Stiffness Coefficients and Allowable Loads for a Nozzle in a Flat bottom Frangible Roof Joint Behavior of Cylindrical Oil Storage 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.File Size 884KBPage Count 15Welded Tanks for Oil Storage; Thirteenth EditionDesignation API STD 650 13TH ED (2020) Welded Tanks for Oil Storage; Thirteenth Edition.Active Monogram Standard.1.1 General.1.1.1 This standard establishes minimum requirements for material,design,fabrication,erection,and inspection for vertical,cylindrical,aboveground,closed- and open-top,welded storage tanks in various sizes and capacities for internal pressures approximating
