PROBLEM TO BE SOLVED: To provide a structure for connecting a rectangular or circular concrete-filled steel tube column (CFT column) and a beam with an H-shaped cross section by using a joint metal and a high-strength bolt, which can enhance the performance (rigidity and strength) of a joint by strengthening the function of anchoring the high-strength bolt to concrete. SOLUTION: An anchor part, which is constituted by coupling an anchor plate 13 and a square tube-shaped or cylindrical tension ring 15 together on the inside of the steel tube column 1, is formed in the high-strength bolt 12 for connecting the column 1 and the joint metals 2a, 2b, 2c and 2d, which abut on one another. The anchor part is embedded in the concrete 6 which is solidified by being infilled into the column 1. COPYRIGHT: (C)2004,JPO
