Equations 4.2-4.4 in axial suggested by Cardoso (2014), were assessed then utilized in the derivation of design equations, to account for material orthotropy. Figs. 4.1– 4.5 present plots of the critical buckling stress, fcr, vs. the aspect ratios(h/b) for RHS sections. The orthotropic conditions are considered in five different cases of orthotropy. Three cases in […]
