Compression Tests of Short Welded I‐Sections
Publication: Journal of Structural Engineering
Volume 112, Issue 5
Abstract
The local buckling and post‐local buckling behavior of short length I‐section columns fabricated by welding high tensile steel plate is described. Six sections of three different section geometries were tested to destruction by loading between rigid end plattens mounted on freely rotating bearings in a compression testing machine. Accurate measurements of welding residual strains and geometric imperfections were taken prior to testing and are presented in the paper. Comparisons of the test local buckling loads are made with a finite strip buckling analysis including welding residual strain. Comparisons of the measured axial stiffnesses and stress distributions were made with a nonlinear finite strip analysis, which includes geometric imperfections and welding residual strain. The test loads are compared with those based on the Winter effective width formulas.
