COMPRESSION TESTS OF WELDED CHANNEL SECTION COLUMNS

The results are presented of a test program on the strength of channel section columns fabricated from high strength steel by welding. Most of the columns were tested between pinned ends and overall buckling occurred in a flexural mode in the plane of symmetry. The test program comprised three different cross sections which are referred to as Series I, II, and III. The plate slenderness ratios varied in the different series from 16-32 for the flanges and from 48-70 for the web. The section geometries were so chosen that local buckling of the sections caused the internal force under uniform compression to move in opposite directions in series II and III and, as a result, overall bending imposed by local buckling occurred in opposite directions in the two test series. In addition to the pin-ended tests, fixed-ended stub column tests were performed on specimens of each series to investigate short column strength. Details are given of the test program and of the findings.
