Investigations of local/global buckling of cylindrical metal silos with corrugated sheets and open-sectional column profiles

Influence of column profile slenderness λcol, silo diameter D and column's distance ds on silo buckling form from FEM and EC3 (silo height H = 10 m, corrugation 18 × 76 mm2 and wall thickness t = 0.7 mm: region 'A' - global buckling forms and region 'B' - local buckling forms122
