Generally, vibration control refers to the absorption of vibration energy by controlling the deformation caused by the horizontal force acting on a building (dissipation). Such a device or structure for vibration damping is referred to as a vibration damping structure. At this time, the lateral force controlled by the damping structure is mainly an external force due to a wind load or an earthquake of a high-rise building.
