Abstract: The paper presents the results of an optimization calculation of two variants of a typical design of a structural coating with dimensions in the plan of 21×30 meters, consisting of pentahedra. Two implementation options were considered: with a cell of 1.5 and 3 meters. Both options are pivotally supported on a rigid contour. The load is considered to be the dead weight of the structure and snow. The load is reduced to nodal using the area method. The optimization parameters were the height of the structure and the lifting boom. The search for the optimal solution is carried out by the method of 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 programming language MATLAB. A feature of the software complex is the ability to exchange data with the LIRA-CAD automatic design system by means of the output text file.
Keywords: structural structures, optimization, boom, mass.
