In this paper are presented integral expressions precise enough for computing the internal forces and vertical displacements of double curvature shallow shells under the action of a concentrated load over a certain distance from the boundary according to the moment theory of shells. In case of shallow shells of equal curvatures, these expressions can be easily integrated into formulae which are exactly the same as those given by E. Reissner, but for shallow shells of unequal curvatures, the solution is given in the form of series composed of Thomson functions, the convergence of which is considered to be quite good in the ordinary scope of application (1 < k1/k2≤2). Furthermore, formulae for the internal forces and vertical displacements of shallow shells of equal curvatures under the action of circular line loads and circular ring loads as well as their exact values at the point of a concentrated load for shallow shells of unequal curvatures are also given in the paper.
