Evaluation of Design Criteria for (Oil) Storage Tanks with Frangible Roof Joints

Describes research that evaluated the ability of the present design criteria (API 650) to ensure the desired frangible joint behavior. Particular questions include: evaluation of the area inequality as a method to predict the buckling response of the compression ring; effect of roof slope, tank diameter, & weld size on the frangible joint; effect of the relative strength of the roof-to-shell joint compared to the shell-to-bottom joint.
