In the article, the formulation and implementation of the task to rationalize the structural parameters of reinforced concrete structurally anisotropic shells are presented. The criterion for such an objective is the energy principle, according to which it is considered that out of the entire set of possible system parameter values with a constant volume of material, the number of external and internal ties, the potential deformation energy after the reconstruction reaches the lower limit at a rational combination of the geometric parameter values. The coatings of buildings and structures perceive significant loads, which cause a high level of the stress-strain state of the system. That is why it is advisable to consider such types of coatings that could perceive, evenly distribute and transfer the load to the supports. Structurally anisotropic reinforced concrete shells of different Gaussian curvature are proved to be the most suitable for this purpose. The search for rational shell designs that perceive the specified types of loads is a rather urgent, but logically unfinished problem.
