PROBLEM TO BE SOLVED: To provide a junction structure of a beam end, capable of improving fatigue resistance and deformability of a beam while avoiding preceding yield of a beam end joint part by low-cost construction, as the junction structure of the beam end in a steel structure with beams constituted of H-steels and the like.SOLUTION: As to a junction structure of a beam end in a steel structure constituted of column 1 and beams 2, the beam end 31 is strengthened by a reinforcing plate 6A consisting of linear sides, and moreover a boring work is applied to a flange 2a of the beam 2 to provide bored parts 7 within a range in a reinforced material axis direction in the beam end 31. Thereby, a beam sectional position 8 where the bored part 7 closest to the column 1 in the material axis direction exists yields opposing to a predicted bending moment distribution. |
