“…Therefore, it was possible to apply the boundary conditions and loads directly to one node, simplifying the modelling process. This also compensates for modelling material zones in the ends of the member with the higher value of Young's modulus of elasticity [29], which prevents the development of stress concentrations under concentrated loads. As there is also analysis of IPE members with free warping of the end cross-sections in this paper, a different modelling technique of such boundary conditions is explained later in the paper.…”

The optimisation of the design method for verification of slender steel beam-columns is still a current issue not only from scientific point of view, but also for design practice. Therefore, the main objective of this paper is comparison of the suitability of established design approaches, according to the European standards for steel and aluminium structures, on the basis of numerical simulations. Thus, a finite element model was validated on the basis of experimental analysis available in the scientific literature. To perform the comparison of accuracy of design approaches according to European standards, a commercial software program ANSYS was used for observation of the resistances of beam-columns. The resistance of european I beams with parallel flanges (IPE) and a rectangular hollow cross-section (RHS) were investigated for four load cases on a simply supported member and also on a pinned-fixed beam column with linear bending moment distribution, where the resistance of the cross-section governs. Finally, the conclusions for suitability of the respective design approaches are discussed, together with some findings that arose from this work.
