<p>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.</p> |
