摘要：
Based on a formulation for the elastic distortional buckling of tapered I-beams, some observations have been developed that are germane to the finite element modelling of the lateral buckling of beams. In particular, it is shown that a commonly cited formulation omits a boundary term, and can in some cases lead to erroneous results. A new set of degrees of freedom for distortional buckling are proposed, and these may be modified easily to account for lateral buckling in the simplified case.
