Comparison of design methods for a tank-bottom annular plate and concrete ringwall

Abstract

This paper studies three design methods for a bottom annular plate of large storage tanks and the design of the concrete ring wall. It is shown that the annular-plate width, thickness, and the width that will project beyond the outer surface of the shell can be calculated analytically. The design of the annular bottom plate and the concrete ringwall is discussed and the need for an accurate representation for the interaction between the bottom plate and the foundation is emphasised.
