Stress Analysis of Anchored Storage Tank with a Ring Wall

Because of the anti-earthquake and dome roof oil-filling, anchoring bolts are often fastened to the outermost edge of the tank bottom's annular plates. At the present, there is no calculating method for this situation of tanks. This paper presents the stress analysis of the shell and bottom plates of the tanks with an outside ring wall and an inside elastic foundation, and gives theoretical calculating equations. This paper is a sequel for 《Stress Analysis of Low-pressure Anchored Storage Tanks》at this Journal, and this paper's other aspects are seen in it.
