Abstract: The article discusses membrane systems of coatings, shells, and positive Gaussian curvature. The analysis of the advantages and disadvantages. The main methods of stabilizing membrane structures on the round and oval planes are given. A system of dimensionless parameters is considered, which makes it possible to determine the stiffness characteristics of the main bearing elements of non-stressed membrane structures. The task is to develop a similar system of stiffness parameters for pre-stressed membrane structures of coatings on a circular plane, taking into account the joint operation of the coating and the underlying structures. A new structural form of the coating is given, which allows constructively creating prestressing in the support contour of the shell, which helps reduce the material consumption of the system. For the most rational work of the material of construction it is proposed to solve the optimization problem of design. As optimization parameters, we consider not only the mass of the coating, but also the mass of the underlying supporting structural elements.
Keywords: membrane, hanging coating, stabilization, prestress, support circuit.
