Abstract:

The objective of this study is to develop a method of reducing wind-induced vibration of long-period structures utilizing sloshing of water in tanks added to the upper part of the structures. The outline of the vibration control damper developed, an analysis of damping effect, and practical application to a tall tower are described.
