Abstract | ABSTRACT: This paper provides an overview of the most recent research activity concerning the (i) nonlinear
behaviour (elastic and elastic-plastic), (ii) ultimate strength and (iii) Direct Strength Method (DSM)
design of cold-formed steel columns experiencing local-distortional (L-D) interaction. After briefly introducing
and illustrating this mode coupling phenomenon, both numerical (Abaqus 4-node shell finite element analysis)
and experimental results are presented, compared and discussed. The numerical investigation make it possible
to characterise the L-D interactive behaviour and failure of columns with different cross-section shapes (lipped
channels, hats, zeds and racks) and includes fairly extensive parametric studies, carried out in order to (i)
assess how the relevance of the L-D interaction effects varies with the ratios between the competing (local and
distortional) critical buckling stresses and the steel yield stress, and (ii) gather a substantial ultimate strength data
bank. Then, the experimental tests, dealing with lipped-channel and rack-section columns, provides experimental
(i) evidence of the occurrence of clear L-D interaction and (ii) failure loads and collapse mechanisms. Next,
after showing the inadequacy of the current DSM local and distortional column strength curves to predict
L-D interactive failures, the paper presents and assesses the merits of recently developed DSM-based design
procedures against such interactive column failures. Finally, the paper closes with some concluding remarks and
a few comments on developments planned for the near-to-intermediate future. |
