LOCAL BUCKLING OF WELDED I- SECTIONS IN COMPRESSION

The local buckling and post-local buckling behaviour 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 stress. Comparisons of the measured axial stiffnesses and stress distributions are made with a nonlinear finite strip analysis which includes geometric imperfections and welding residual strain.
