description PROBLEM TO BE SOLVED: To provide a rational, effective, and appropriate junction structure for easily joining a steel-frame beam to a reinforced concrete column.SOLUTION: A steel-frame beam 2 is joined to a column head part or corbel of a reinforced concrete column (RC column 1) by a plurality of anchor bolts 4 substantially in a form of relatively rotatable pin joint. A bearing part 20 composed of a base mortar is formed between the steel-frame beam and the column head part or corbel. The bearing part is formed between the anchor bolts arranged at an interval in the axial direction of the steel-frame beam, and a horizontal shear force is made transmittable between the steel-frame beam and the column head part or corbel via the bearing part. The position of bar arrangement is set in such a manner that a virtual stress action line S by resultant force of a bearing force and the horizontal shear force passes through at least the inside of shear reinforcement bars 6a of the upper most stage arranged in the column head part or stirrups of the uppermost stage arranged in the corbel.
