PROBLEM TO BE SOLVED: To provide a design method for a structure for joining columns together, which can prevent a side wall of a joint steel pipe from causing out-of-plane deformation, even when a horizontal force acts on the joint steel pipe, and the structure for joining the columns together.SOLUTION: Fillet welding makes ribs 37 provided in upper and lower parts of an inner peripheral surface of a side wall except a corner part 39 of a joint steel pipe 31 in such a manner as to protrude inward from the inner peripheral surface. The upper rib 37 of the joint steel pipe 31 has such shape dimensions as to satisfy the following conditional expressions (1)-(5).SELECTED DRAWING: Figure 1 【課題】接合鋼管に水平方向の力が作用しても接合鋼管の側壁に面外変形が生じることを防止できる柱同士の接合構造の設計方法及び柱同士の接合構造を提供する。【解決手段】接合鋼管３１の隅角部３９を除く側壁の内周面における上部及び下部に、リブ３７が内周面から内側に突出するように隅肉溶接により設けられ、接合鋼管３１の上部のリブ３７は、下記の条件式（１）〜（５）を満足するような形状寸法とすることを特徴とする。［数１］［数２］【選択図】図１
