To provide an effective and appropriate vibration control structure which has little constraint on floor planning and is capable of being widely applied to general buildings.
Vibration control devices 10 are intensively installed on vibration control floors which are allocated to lower floors. A cross sectional area of columns on the vibration control floors is smaller than the cross sectional area of the columns on upper floors so as to reduce a story stiffness of the vibration control floors compared to the story stiffness of the upper floors. Column main reinforcement of the columns 1 on the vibration control floors and the same of the columns 2 on an immediate upper floor are connected by fixing the both reinforcement to a panel zone in a state that the column main reinforcement of the columns 1 on the vibration control floors is arranged inside the column main reinforcement of the columns 2 on the immediate upper floor. The column on the vibration control floor is made of a reinforced concrete column with high strength or ultra high strength concrete and high strength or ultra high strength reinforcement. Furthermore, the reinforced concrete column is clad with reinforcement steel. The vibration control devices 10 are installed inside a steel frame which is fixed inside a structure frame made up of the columns and beams on the vibration control floors.
