Abstract
To suppress vibration on a long-span floor, caused by traffic and walking, Tuned Mass Damper (TMD) is usually set up. However, TMD can not adapt to vibration caused by an earthquake because of limitation of stroke of TMD. Therefore a new TMD that is adaptable to both traffic vibration and earthquake vibration is required. Then this paper aims at research and development of the vibration control device that adapts to tboth traffic and earthquake vibration. The vibration control performance for earthquake depends on the parameter of the buffer material. The displacement after impact is decreased by an increase of stiffness of buffer material. However, vibration control performance decreases because the impact force grows.
