Abstract

There are many researches about the structual behavior of electric resistance welded tube, but few researches about that of spiral steel pipe, which is mainly used for steel pipe pile. The deformation capacity of the member is improved by preventing local buckling of wall elements because welded part of spiral steel pipe is spiral and the seam welded part is thicker than wall elements of steel pipe. In this study, local buckling behavior of spiral steel pipe is clarified by stub column test of these kinds of pipes. We investigate the local buckling strength and deformation capacity of spiral steel pipe by previous experimental formula for electric resistance welded tube inthis paper.
