<P>PROBLEM TO BE SOLVED: To provide a reinforcing structure of a steel column-beam joint portion, capable of reinforcing the steel column-beam joint portion without requiring welding at site when the steel column-beam joint portion is joined to a reinforcement metal fitting. Ž<P>SOLUTION: The reinforcement metal fitting 4 is attached to the joint portion between a steel pipe column 1 and an H-steel beam 2. The reinforcement metal fitting 4 includes a bottom plate part 4a, which is installed substantially vertically so as to abut against the surface 1a of the column 1 joined to a beam; an arm part 4b which generally horizontally projects from the bottom plate part 4a along the longitudinal direction of the beam 2 and holds the lower flange 2a of the beam 2 and which is formed in a generally groove shape in cross section; and a reinforcement rib 4c formed integrally with the bottom plate part 4a and the arm part 4b between the bottom plate part 4a and the arm part 4b.
