The article sets the task of determining the area of effective application of solid and through columns. The parametric optimization method is used as a research method. The accepted optimality criterion includes the cost of steel, the cost of column manufacturing and the cost of applying corrosion protection. The main parameters affecting the intensity of metal and cost of the column are the load, the calculated length and the radius of inertia of the section. In the study, the type of cross-section of the column is adopted unchanged, in the form of an I-beam (is a limitation); the load and length of the column are taken as variable parameters. The design scheme of the structure is a centrally compressed column with hinged fastening of the base and the head. According to the regulatory conditions of stability and ultimate flexibility, the required cross-sectional area for each value of the variable parameter is determined. Charts with selected areas of optimal application are compiled; it helps the design engineer to choose between a solid or through section of the column, depending on its actual load and length.
