ABSTRACT:
A new mass damper that avoids the formation of a higher-order resonance by utilizing the inertial resistance of a flowing liquid is disclosed. This damper solves the problem of an additional new degree of freedom due to the additional mass system associated with the conventional mass damper and makes it possible to control random vibration with a broad spectrum such as earthquakes. Also, several examples in which this damper is used for multilevel structures are disclosed.
