Abstract
Despite the increase in the growth rate of construction with the use of steel thin-walled sections, the building code for the design and calculation of these structures has a number of conventions and indicates the preferred use of the results of experimental studies in the design. Full-scale tests are generally not available during design, so numerical modelling is a correct alternative. The analysis of existing scientific literature shows that there is no consensus among researchers regarding the main parameters of the models and the modelling algorithm in general, so the aim of the paper is to develop recommendations for modelling thin-walled sections. The results of the study for object made from a coupled sigma profile under axial compressive force conditions let us develop key recommendations for modelling including the use of finite element type, finite element mesh parameters, the mechanism of application of boundary conditions, external loads and other model parameters. The results were verified by analytical methods of thin-walled sections calculation. The obtained convergence of the results indicates the possibility of using these recommendations in the design and calculation of thin-walled structures.
