The elastic buckling properties of rectangular plates and cold-formed steel beams and columns, including the presence of holes, are studied with thin shell finite element eigenbuckling analysis. Buckled mode shapes unique to members with holes are categorized. Parameter studies demonstrate that critical elastic buckling loads either decrease or increase with the presence of holes, depending on the member geometry and hole size, spacing, and location. Simplified alternatives to FE elastic buckling analysis for members with holes are developed with classical plate stability equations and freely available finite strip analysis software.... 5.5 Novotechnik position transducer with ball-jointed magnetic tip 166 Figure 5.6 Central Machinery metal band saw ... the column specimens 169 Figure 5.10 The intermediate length specimens were end-milled in a manual milling machine anbsp;...
