Resumo
This study presents an experimental investigation into the behavior of steel storage rack perforated uprights
under axial compression. A total of 44 prototypes comprising eleven cross-sections and four lengths were tested,
and a buckling curve of the studied uprights is proposed. The focus of the study is to compare the ultimate loads
of the experimental uprights by numerical and theoretical analysis, through modifications to the direct strength
method (DSM) equations, using the Brazilian and European design codes. The theoretical values obtained are
smaller than the experimental ones, and the interaction of distortional and global buckling is also discussed. The
ultimate loads obtained with the proposed buckling curve were less conservative than the DSM equations.
