PROBLEM TO BE SOLVED: To control the bending deflection of a high-rise building caused by an earthquake, a typhoon, etc., by rigidly connecting a rigid beam to a core frame structure of the high-rise building and supporting the end of the rigid beam through a damper. SOLUTION: A rigid beam 4 reaching an outer peripheral frame structure 3 is rigidly connected to both ends of the core frame structure 2 of a high-rise building as a vibration control structure 1. The ends 4a of the rigid beam 4 are supported through vertical dampers 6 by damper supports 5 erected on a foundation 7. Further, for a higher high-rise building, the rigid beams 4 are disposed in upper and lower two stages, and damper supports 5 and dampers 6 are arranged between upper and lower rigid beams 4 and between the lower rigid beam 4 and the foundation 7 respectively. In this case, the damper supports 5 and the damper 6 disposed between the lower rigid beam 4 and the foundation 7 can be omitted. In this way, a bending deflection of a high-rise building generated caused by axial extension/contraction of a column in an earthquake, a typhoon, etc., can be transmitted to a vertical damper 6 through the rigid beam 4 to attenuate and control the vibration.
