Abstract

Thin Walled Cold-Formed Concrete Filled Tubular Square Column are manufactured by flare welding at center of column width for cold formed L shape plates of 4 piece and improved composite effect of concrete and steel by vertical inner anchor. Also, Axial resistance of concrete is increased by confine effect of steel tube and steel prevent local buckling of steel column. In this study, we introduced manufacture method of thin walled cold-formed square column steel square concrete filled tubular column and structural performance of the welded built-up square stub column was verified by structural test for ten specimens with parameters of concrete strength, type of steel tube, width to thickness ratio of steel tube.
