PROBLEM TO BE SOLVED: To provide a structure for tension-joining a concrete-filled square steel-pipe column and a beam together by using a high tension bolt, which employs a joint metal and the high tension bolt, and which can raise the highest proof stress of a joint by efficiently increasing the rigidity and tensile proof stress of the joint through the use of a simple structure.;SOLUTION: In the structure for tension-joining the concrete-filled square steel-pipe column and the beam together by using the high tension bolt 3, both side parts of the joint metal for joining the beam 4 to the square steel-pipe column 1 are tension-joined to a part near a corner part of the column 1 by using the high tension bolt 3; tension resisting and reinforcing members (a through-bolt 5 and the high tension bolt with an anchor function) with a shank for being embedded in concrete 6 inside the column 1 are inserted/fastened into the area, between the high tension bolt 3 and a tension joint, of the joint metal; and the concrete 6 is filled into/solidified in the column 1.;COPYRIGHT: (C)2007,JPO&INPIT
