ABSTRACT
The aim of this paper is to
interpret the effect of lateral restraint on buckling behaviour of a Z-cross
section column subjected to pure axial load. Adequate analytical solutions are
compared with the numerical and experimental results obtained for specimens
both laterally free and those restrained by trapezoidal steel sheeting.
Compared to the unrestrained column, a large relative increase of critical
loads is detected. Therefore, further optimization of such structural elements
is possible.
KEYWORDS
Z-section column, lateral restraint, buckling resistance, finite element method.
