Abstract:

This paper presents the state-of-the-art in damping systems for controlling wind induced motion of structures and their applications in the U.S. and Japan. Both passive and active systems are presented and their highlights and shortcomings are discussed. The damping devices include passive dampers consisting of tuned mass dampers, liquid or sloshing dampers, hybrid liquid dampers and active mass dampers. The paper includes a brief discussion of the theoretical background, applications and performance of currently installed systems.
