A unified resistance verification of beam-columns not susceptible to LT-buckling

Marian Giżejowski , Radosław Szczerba , Marcin Daniel Gajewski


In this paper, a unified verification method of both the design cross-section resistance and the overall stability of steel structural members not susceptible to lateral-torsional buckling is proposed. The case of combined planar bending about one of the section principal axis (y or z) and axial compression is considered. The unified analytical proposal developed herein is verified by the comparison of its results with those of numerical simulations for beam-columns bent about y-y axis. Therefore, geometrically and materially nonlinear analysis with all the second order effects and geometrical imperfections taken into account (GMNIA is the abbreviation used hereafter) is carried out. Numerical analysis is performed with use of ABAQUS/Standard finite element software in which an appropriate shell modeling technique is utilized. Numerical study is carried out for a chosen hot-rolled section and it includes the influence of relative slenderness ratio of beam-column elements on the buckling resistance. Concluding remarks are drawn and directions of future research are outlined.
