Abstract
The objective of this research is to examine the stability of perforated cold-formed steel members subjected to combined axial and bending loads. Preliminary design formulations of the Direct Strength Method in non-perforated cold-formed steel beamcolumn indicated that under combined actions, linear interaction assumption for predicting strength of cold-formed steel is conservative in comparison with direct-analysis prediction that considers stability and yielding of cold-formed steel beam-columns under the appropriate stress combinations. Perforated cold-formed steel members subjected to combined loading are commonly used in cold-formed steel framing industry and it is important to extend the beam-column stability examination to perforated members as well. Complete yielding and stability solutions under direct combined actions for perforated sections are established. These elastic buckling envelopes form the basis for formulating a preliminary Direct Strength Method and together with collapse analysis provide valuable analytical background in future experimental testing of perforated cold-formed steel beamcolumns.
