Reduction of Low-frequency Vibrations of Wooden Floors by Tuned Mass Dampers

摘要

Over the last decade a steady increase of public and industrial buildings in the wood building construction sector has occurred. Often these buildings are built with wide spanned floors. These floors tend to induce unpleasant low-frequency (5-100Hz) vibrations. These low-frequency vibrations affect the inhabitants in two ways: namely through vibrational sensitivity of course, and also as noise.
