PROBLEM TO BE SOLVED: To suppress out-of-plane deformation on both ends of a diagonal member of a bearing frame. SOLUTION: The structure of the bearing frame includes diagonal members 13, 14. Each of the diagonal members 13, 14 includes a brace core material 22 and a stiffening member 30 which prevents the buckling of the brace core material 22. The stiffening member 30 includes a pair of inner stiffening members 23 fitted to both outer sides of the brace core material 22, and a tube-like outer stiffening member 24 binding the pair of inner stiffening members 23 and the brace core material 22 together. The brace core material 22 and the pair of inner stiffening members 23 respectively have extending parts 22A, 23A of which both longitudinal ends extend outward beyond the outer stiffening member 24. End constraining means 25 preventing the extending parts 23A of the inner stiffening materials 23 from separating from the brace core material 22 are fixed to the extending part 22A of the brace core material. The end constraining means 25 are fixed to each of a first column member 4 and a second column member 12 by the intermediary of a pair of mounting plates 28 sandwiching the end constraining means from both outer sides and extending on the plane parallel to a vertical plane of structure.
