Kurniawan, Cyrilus W. & Mahendran, Mahen (2007) Lateral Buckling Behaviour and Design of the New LiteSteel Beam. In Wang, Y.C. & Choi, C.K. (Eds.) Third International conference on Steel and Composite Structures, August 2007, Manchester UK.
The flexural capacity of the new hollow flange steel section known as LiteSteel beam (LSB) is limited by lateral distortional buckling, which is characterised by simultaneous lateral deflection, twist and web distortion. Recent research into this unique buckling behaviour has developed appropriate design rules for the member capacity of LiteSteel beams. However, these rules are limited to a uniform bending moment distribution and do not take into account the effects of non-uniform moment distributions and load heights. Many steel design codes have adopted equivalent uniform moment distribution and load height factors to ac-commodate different loading conditions. However, past investigations have shown the inadequacy of these factors to different cross sections and materials. This paper describes the effects of non-uniform moment dis-tribution and load height on the lateral buckling strength of LSBs based on finite element analyses of LiteS-teel beams. It presents the finite element analysis results and a discussion of suitable design methods for LSBs subject to non-uniform distributions and varying loading positions
