PROBLEM TO BE SOLVED: To provide a rigid frame structure improving earthquake-proof property by applying bending moment to a support column in the reverse direction to bending moment generated by a beam, reducing the bending moment applied to the support column in advance, and suppressing horizontal displacement. SOLUTION: This rigid frame structure is constituted by erecting support columns 1, 2 made of steel across a predetermined interval and stretching and providing the beam 3 between column heads 1a of the support columns 1, 2. Brackets 4, 4 are attached to the column head 1a of the support column 1 on an outer side across an interval in the vertical direction, and the brackets 4, 4 are tightened by a bolt 5 to generate being moment on the column head 1a and cancel and reduced bending moment applied on the column head 1a by the beam 3.
