The crush characteristics of thin-walled flanged columns with circular and octagonal cross-sections were studied. Specimens tested were fabricated by spot welding together along the flanges, two separate sections of formed 1018 CR steel sheet metal. The flange width was varied for each of the three different thicknesses considered. Loading was limited to pseudo-static uniaxial compression for all specimens.Triggering devices consisting of drilled holes and notches cut out of the flanges were investigated. The holes were found to increase the structural effectiveness of the flanged cylinders, whereas the notches caused a decrease in absorbed energy. The most promising members however were the flanged octagonal columns with the minimum flange width. Larger flange sizes were found to cause global buckling modes and loss of structural effectiveness.
