Viscoelastic dN and tuned mass dampers are often used by tall building designers to control wind-induced building vibrations resulting from such phenomena as vortex shedding, galloping, flutter, etc. Such vibrations depend to a large degree on the building's geometry and dynamic characteristics and the local wind climatology. In this article, the dynamic behavior of tall buildings equipped with tuned mass dampers is studied. The application of the tuned mass damper device is illustrated by an example involving a 125-story steel framed super-tall building planned for the Los Angeles area.
