Abstract
Introduction. The article deals with methods of determining the design values of the bearing capacity of a thin-walled rod experiencing compression deformation (taking into account the probable local buckling) according to domestic and European normative documents and the design standards of North America.
Materials and methods. Calculations for thin-walled cold-formed C-shaped steel sections were carried out. Methods such as collection and systematization of information data, theoretical generalization of materials obtained in the analysis of domestic and foreign normative and technical documents, comparative analysis were used.
Results. The comparison of methods for determining the load-bearing capacity of thin-walled rods under local buckling was made. The calculation algorithms are presented in tables. The results are summarized in unified tables.
Conclusions. Based on the analysis of results (taking as a reference for comparison the load-bearing capacity determined in accordance with SP 260.1325800.2016) a difference of 5 with EN 1993-1-3 and 12 % with AISI S100–16 was obtained. Graphs of correspondence between the load-bearing capacity and geometric characteristics of the cross-section (height, width and thickness) are shown. They give a visual representation of the difference in approaches to the development of normative and technical documents in different countries.
