VERTICAL VIBRATION TUNED MASS DAMPER AND VERTICAL VIBRATION ATTENUATION SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a vertical vibration tuned mass damper or the like, capable of effectively damping vertical vibration of a damping object resulting from vibration of a horizontal brace or the like.;SOLUTION: The damper comprises a mass 3 mounted on a longitudinal middle part of the horizontal brace 2 that is a restoring force element, and a sponge-like damping material 5 provided between the mass 3 and a floor board 4 above it to damp vertical vibration of the floor board 4. The mounting position of the mass 3 to the horizontal brace 2 is preferably made to be changeable in the brace longitudinal direction.;COPYRIGHT: (C)2009,JPO&INPIT
