Abstract

An interaction of uniaxial bending and axial compression occurs very often in engineering practice and has been widely described in clause 6.2 of Eurocode 3. There are appropriate formulae given to verify the design cross-section resistance of steel structural members. Numerical aspects of constructing the cross-section resistance interaction curve of I-sections are presented in this paper through numerical modelling of the behaviour of stocky beam-columns with the relative slenderness ratio of 0.2 that distinguishes the range of characteristic values of the cross-section resistance and the member buckling resistance. Numerical study was carried out with respect to hot-rolled wide flange HEB/HEAA sections. The case of combined planar bending about one of the section principal axis (y or z) and axial compression was considered. The scope of numerical research includes different cross-section classes from class 1 to class 4. In case of cross-sections from class 1 to class 3, Geometrically and Materially Nonlinear Analysis (GMNA) is carried out. As far as class 4 cross-sections are concerned, Geometrically and Materially Nonlinear with Imperfections Analysis (GMNIA) is carried out in which geometrical imperfections due out-of-flatness deformations of section plate components are taken into account in the form of first local buckling mode. Plate section components are modelled using Finite Shell Elements (FSEs). FSE modelling technique using ABAQUS/Standard library is utilized. Numerical results in the form of interaction diagrams are compared with those of analytical ones presented in Eurocode 3. Differences occurring between the results from conducted FE analysis and those obtained with use of Eurocode’s interaction formulae are discussed and factors causing these differences are outlined. Concluding remarks are drawn.
