Abstract
This paper investigates vibration suppression effect of novel Tuned Mass Damper, namely Wired Tuned Mass Damper (WTMD). WTMD is a tuned mass damper made of an auxiliary mass connected with two small masses with wires. The weights of t small weights give the main auxiliary mass restoring force, while the wires allow the main mass to move over longer stroke than ordinary springs allow. In this study, an experimental structure and WTMD is built, and WTMD's property is investigated.
