Mesh building of a toroidal shape with various grid schemes

The object of research is a spatial system of a regular toroidal structure with different cell shapes. The purpose of this work is to analyze mesh domes with different design schemes. The considered load, evenly distributed on all elements of the spatial structure. Method. Finite element method in the LIRA-SAPR software package used to determine the qualitative and quantitative indicators of the bearing capacity of the spatial coverage. Results. The analysis of technical and economic indicators for various options for the shape of a building cell and various materials was carried out, as a result of which it was established that the structure using trapezoidal cells is the most optimal; the smallest material consumption is the design using trapezoidal cells; when comparing the material consumption, the most economical option was made of wood, the weight of the wood structure is 81% of the weight of the metal structure.
