摘要

Based on an analytical method, a parametric study is carried out on the bending response of steel beams with box cross-sections. Slenderness requirements for the classification of these beams are proposed, taking into account the interactive effects of flange and web local buckling. These serve as limits for application of different methods for analysis of steel framed structures. The present study is a continuation of a previous research of the authors on I-beams, where the detrimental influence of lateral-torsional buckling, coupled with the combined effects of the local buckling modes, has been clearly demonstrated. It has been shown that the usual cross-section classification deserves a generalization in terms of member classification.
