The wall and the base plate are further assumed to be constructed monolithically. The structure is separated into three domains as follows: (a) a cylindrical shell, (b) a circular base plate within the cylindrical shell, and (c) an annular base plate outside the cylindrical shell. The stress resultants are obtained from the solution of the three equations governing the shell and the plates. It is observed that, in comparison with the proposed method of analysis, a cylindrical tank designed by the conventional method assuming the shell to be fixed at the base may be unsafe at the base; and, if designed by assuming uniform subsoil reaction, the structure would be too conservative.

The problem of a cylindrical water tank is analyzed by the assumption that the base plate rests on an elastic foundation of Winkler type and its wall is an infinite long cylindrical shell. The wall and the base plate are further assumed to be constructed monolithically. The structure is separated into three domains as follows: (a) a cylindrical shell, (b) a circular base plate within the cylindrical shell, and (c) an annular base plate outside the cylindrical shell. The stress resultants are obtained from the solution of the three equations governing the shell and the plates.
