Abstract
This discussion deals with the stresses induced in a spherical pressure vessel due to the constraining effect of a cylindrical skirt. The skirt is taken as being made of two sections having different thicknesses, one section being located inside the vessel and the other directly underneath on the outside of the vessel.
Expressions are obtained for the bending moments and shear forces induced in the vessel and its skirts when (1) the vessel is stressed by a uniform radial pressure and (2) the skirts are loaded in an axial direction. The general case of an arbitrary load system is also considered and expressions are obtained for the induced moments and shear forces in terms of a set of constants which can be evaluated readily when dealing with any particular problem.
In an appendix the general solution is used to consider briefly the particular cases (a) Temperature gradient in the bottom skirt. (b) Self weight of the vessel, (c) Axial load on the vessel.
