The main purpose of this paper is to recompose the geometrical non-linear theory of thin elastic shells with the aid of the improved generalized variational principle into which we introduced the expression of Kirchhoff-Love assumptions and the generalized boundary conditions. As the stationary conditions of the functional in this principle, we obtained unifyingly the non-linear basic equations for general shaped shells with terse expression. For those application, we formulated the approximate method on the basis of the principle of virtual work for rotational shells with edge rings subjected to axisymmetrical loads. The effect of edge rings was considered as statically indeterminate forces on the boundary, which derived with the aid of the linear beam theory.
