Compression Tests of High Strength Steel Channel Columns with Interaction between Local and Distortional Buckling
Publication: Journal of Structural Engineering
Volume 130, Issue 12
Abstract
This paper describes a series of compression tests performed on lipped channel section columns fabricated from cold-reduced high strength steel of thickness with nominal yield stress . The test results presented in the paper are the third stage of an Australia Research Council research project entitled “Compression Stability of High Strength Steel Sections with Low Strain-Hardening” A range of lengths of lipped channels with intermediate stiffeners in the web and the flanges were tested between fixed ends to determine the strength of the sections. For the lipped channel sections, failure resulted from local and distortional buckling with interaction between these modes. The tests indicated that distortional buckling and the interaction of local and distortional buckling may have a significant effect on the strength of the sections formed from such thin high strength steel. The paper presents the results obtained experimentally and theoretically using the effective width method and the direct strength method, neither of which account for interaction of local and distortional buckling.
