Buckling of Four Equal‐Leg Angle Cruciform Columns
Publication: Journal of Structural Engineering
Volume 109, Issue 2
Abstract
The elastic and inelastic buckling of cruciform section columns formed from four equal leg angles is examined. The elastic critical loads for flexural, torsional and plate building are determined. Two different and extreme assumptions are made about the residual stress distribution from which the tangent and reduced modulus buckling loads are determined for the elastic core of the section. The results of this analysis are compared with empirical methods in current specification and indicate that the specifications are not conservative for all values of slenderness and width‐thickness ratios.
