In the modern construction, shipbuilding, mechanical, aircraft engineering and other fields of industry structures in the form of shells, including orthotropic shells, gained widespread currency. In order to raise their rigidity they are strengthened by reinforcing elements (ribs). In the process of shell constructions’ design the choice of rational construction parameters is very important (rational placement of ribs, their rigidity, curvature). The volume of the shell material is usually a minimalised efficiency function. At that the limit values of stress level in the shell and its stability are the restrictions. It is proposed to use variation and parametric method for choosing the angle and reinforcements by stiffening plates so that the shell construction would not lose its stability and reliability. The applied method with change of continuation parameters gives a scheme of coordinate-wise incline, which provides relative simplicity of choosing rational construction type in case of the given loads and restrictions on its stress-strain state.
