一般注記This thesis proposes a new method to attenuate the dynamic response of long-period structures using Coriolis effect. The effect of vibration control of the Coriolis inducing dampers is investigated numerically and analytically. Two methods are proposed, one consisting of a moving mass with cyclic motion which is applied to tall building structures and the other consisting of unidirectional water-flow which is applied to ship rolling. Furthermore, the first method requires carefully synchronised control as well as larger angular motion for effective damping. An enhanced Coriolis effect damping system is proposed using Fuzzy logic controllers. The newly proposed method incorporates a traditional mass damper coupled with the Coriolis effect inducing system which allows for better performance. The results presented open the door for alternative approaches to vibration control of flexible and rolling structures with low inherent damping.
