Title:
VIBRATION CONTROL BUILDING AND BUILDING VIBRATION CONTROL METHOD
Document Type and Number:
Japanese Patent JP2015200125
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a mass damper type vibration control system which exerts a vibration control effect on vibration not only in a primary mode but also in higher modes.SOLUTION: A vibration control building 10 comprises: a building 20 as a vibration control object; an external structure 30 which is arranged along a periphery 20A of the building 20, with an upper section thereof supported by the building 20 in a manner that allows the external structure 30 to have a relative displacement with respect to the building 20 in horizontal directions through bearings 50 having restoring force in the horizontal directions and a lower end thereof separated from a foundation 1 of the building 20 in a manner that prevents a foundation 1 of the building 20 from direct input of earthquake force, and functions as a mass damper for the building 20; and a plurality of vibration control dampers 40 connecting the building 20 and the external structure 30 on a plurality of levels so that respective vibration control dampers 40 deform in accordance with relative displacements therebetween to absorb vibration energy of the building 20.
