Stability response of flexibly connected cold-formed steel space frames
AbstractResults for the elastic (bifurcation) stability analysis of cubic space frames composed of bisymmetrical cold-formed steel sections are presented. The influences of flexible connections and partial warping rigidity are considered. Calculation of the critical load is based on a finite element eigenvalue algorithm which combines a secant iteration, determinant search routine with a ‘shifted’ inverse iteration strategy. A parametric study on the effect of connection and warping rigidity for the frames subjected to gravity and lateral twist loading is presented. Effects of column orientation and member stiffness on frame stability are discussed.
