Abstract
The optimisation of the design method for verification of slender steel beam – columns is still current issue not only from the scientific point of view, but also for design practice field. The actual behaviour of slender steel members subjected to a combination of axial compressive force and bending moments which arises due to the eccentricity of compressive force, is included in the calculations relatively complex but not sufficiently accurate. The aim of this paper is comparison of suitability of established design approaches, according to the European standards, on the basis of parametric numerical analyses results. Comparing results to the values obtained from the experiments of the beam-column resistances, it is possible to accurate recommendations for the use of different types of design procedures under currently applicable European standards in EN 1993-1-1, EN 1999-1-1 and their National Annexes.
