Annotation: The paper presents the results of the optimization calculation of two variants of a typical structural coating design with a plan size of 21×30 meters, consisting of pentahedra. Two implementation options were considered: with a cell of 1,5 and 3 meters. Both variants are pivotally supported on a rigid contour. The own weight of the structure and snow are considered as the load. The load is reduced to the nodal one using the area method. The optimization parameters were the height of the structure and the boom of the lift. The search for the optimal solution is carried out by the method of the deformable Nelder-Mead polyhedron. The target function of the search is the mass of the structure. Optimization calculation is performed in the author’s software package, which is implemented in the MATLAB programming language. A feature of the software package is the ability to exchange data with the LIRA-SAPR automatic design system by means of an output text file.
Keywords: optimization, deformable polyhedron method, spatial rod constructions, finite element met-hod, programming, MATLAB.
