WELDED BOX COMPRESSION MEMBERS WITH LOCAL BUCKLING

An experimental and theoretical study is presented on welded box compression members of high strength steel. The member cross- sections are composed of plates with relatively large width- thickness ratios so that local plate buckling is supposed to occur before the attainment of the overall member buckling. A total of 25 members of various lengths, width- thickness ratios and cross- sectional shapes (square or rectangular box) were tested to failure under bending as well as under concentric or eccentric axial loading. In the theoretical study a computer program has been developed, based on the effective width concept, to trace up to collapse the load- deformation characteristics of locally buckled beam- columns. By comparing the experimental and theoretical results it has been found that the agreement is reasonably good in the columns with larger width- thickness ratios. (Author/TRRL)
