Abstract
A combination active and passive mass damping device to attenuate vibrations in a structure caused by seismic and/or wind forces. A mass is actively rendered vibratable by a hydraulic actuator and passively vibratable by use of springs. The device normally functions as an active mass damper, but, in the event of a power failure, is automatically converted by a failsafe means into a passive mass damping mode.
