Abstract: PROBLEM TO BE SOLVED: To provide a vibration-controlled base-isolated structure which exerts not only a vibration control function but also a base isolation function against a force imposed on a construction, by an earthquake. SOLUTION: The vibration-controlled base-isolated structure is provided for a column member 3 of a building having a height, and exerts not only the vibration control function of absorbing kinetic energy generated by rolling of an earthquake or the like, and reducing bending moment and axial force imposed on the column member 3, but also base isolation performance by shielding the bending moment and the axial force transmitted from a foundation portion 1 to the column member 3. According to the structure, the column member 3 of the building is axially divided at a bearing portion or some midpoint of the column, and an upper divided section 21 and a lower divided section 22 are connected together by a plurality of axially extending vibration-controlling base-isolating rods 26 each formed of low-yield-point steel.
