PROBLEM TO BE SOLVED: To provide the beam-column connection structure of steel structure, in which structural performance in the beam-end connecting section of a steel- structure frame can be improved without increasing the number of high-strength bolts by supplying the shortage of connection strength in the connecting sections of the web of a steel frame, to which a scallop is formed, and a column. SOLUTION: The flange end of a steel beam 11 composed of H-steel is welded onto a column 10 having steel structure while the web 11b of the steel beam 11 and the column 10 are joined by high-strength bolts 14 through a metallic material 13. A length range of 1/3-1 of the beam depth of the steel frame 11 from the flange end of the steel beam 11 is constituted of a steel-plate flange 15 in thickness thicker than other flange sections 11a.
