PROBLEM TO BE SOLVED: To provide a column jointed structure in which axial force transmission efficiency is ensured.SOLUTION: In a column jointed structure, a first column 1 of RC structure and a second column 2 of S structure or CFT structure are jointed. A jointing steel tube 3 is arranged so as to extend along with column axis direction. Lower part of the second column is fixed in filling concrete 31 which is positioned inside of the jointing steel tube and fills up the jointing steel tube. Upper parts of a plurality of column main reinforcements 11 of the first column are arranged inside of the jointing steel tube and fixed in the filling concrete, and arranged at periphery of the second column in the jointing steel tube. The height of the section from base plate of the second column to lower edge of the jointing steel tube is determined in a manner where smaller one of axial reinforcement in section H ranging from a base plate 22 of the second column to the lower edge of the jointing steel tube or axial reinforcement in section X as the column height of the first column to the lower edge of the jointing steel tube is regarded as axial reinforcement of the column jointed structure. 【課題】軸力伝達性能が確保された柱接合構造を提供することを目的とする。【解決手段】ＲＣ造の第一柱１と、Ｓ造又はＣＦＴ造の第二柱２と、を接合する柱接合構造において、柱軸方向に沿って延在する接合鋼管３が備えられ、第二柱の下部が、接合鋼管の内側に位置して接合鋼管内に充填された充填コンクリート３１内に定着されており、第一柱の複数の柱主筋１１の上部が、接合鋼管の内側に位置して充填コンクリート内に定着されていると共に、接合鋼管内において第二柱の周囲に配置されており、第二柱のベースプレート２２から接合鋼管の下端までの区間Ｈにおける軸耐力と、接合鋼管の下端までの第一柱の柱高さ区間Ｘにおける軸耐力と、のうちの小さい方を当該柱接合構造の軸耐力として、第二柱のベースプレートから接合鋼管の下端までの区間の高さ寸法が決定される。【選択図】図１
