ABSTRACT: The results of a numerical (Abaqus shell finite element analysis – SFEA) investigation con-
cerning the relevance of local-distortional (L-D) interaction effects on the ultimate strength of fixed-ended
lipped channel columns are presented and discussed. The columns analysed exhibit various geometries and yield
stresses, ...
