Installation structure of tuned mass damper, tuned mass damper, and installation method of tuned mass damper

摘要

To suppress locking vibration of a mass body.SOLUTION: A tuned mass damper is configured such that a mass body arranged above or below an object subjected to vibration control vertically vibrates in synchronization with vertical vibration of the object subjected to be vibration control, thereby suppressing vertical vibration of the object subjected to vibration control. The tuned mass damper comprises: a viscoelastic member directly or indirectly provided to the object subjected to vibration control, and supporting the mass body; and at least three elastic members provided in parallel with the viscoelastic member, arranged at a position farther away from a gravity center of the mass body than the viscoelastic member, and supporting the mass body.SELECTED DRAWING: Figure 2
