PROBLEM TO BE SOLVED: To restrain an increase in a cross section of a flexural resistance member, and to facilitate construction in a vibration control structural member of a type of inserting the flexural resistance member inside an outside axial force member used for a brace member. SOLUTION: The flexural resistance member 2 such as a cage, shape steel, and a steel pipe is inserted inside a closed cross-sectional axial force member 1 such as a steel pipe arranged outside the vibration control structural member, and bearing axial force to restrain bucking of the closed cross-sectional axial force member 1. Buckling stiffening efficiency is improved by eliminating clearance by filling a grout material 3 for filling up clearance between the closed cross-sectional axial force member 1 and the flexing resistance member 2. An increase in the cross section of the flexural resistance member is restrained, and the clearance is filled up with the grout material to dispense with strict clearance control between the closed cross-sectional axial force member and the flexing resistance member.
