Frangible Roof Joint Behavior of Cylindrical Oil Storage

This paper presents the results of an investigation into the frangible joint behavior of tanks designed to API 650 rules.In such tanks,the roof-to-shell joint is intended to fail in the event of overpressurization,venting the tank and containing any remaining fluid.The reasoning behind present API design formulas isAtmospheric Storage Tank Specification (Supplement toAPI 650,Welded Steel Tanks for Oil Storage.Together,this Practice and .API 650 .provide requirements for the construction of atmospheric storage tanks. 5.1.5 Typical Joints .5.1.5.1(c) Shell courses on open top tanks and tanks with external or internal floating roofs shall be flush-stacked on the inside.Shell courses onAtmospheric Storage Tank Specification (Supplement toAPI 650,Welded Steel Tanks for Oil Storage.Together,this Practice and .API 650 .provide requirements for the construction of atmospheric storage tanks. 5.1.5 Typical Joints .5.1.5.1(c) Shell courses on open top tanks and tanks with external or internal floating roofs shall be flush-stacked on the inside.Shell courses on
