✦ Synopsis

Some ad hoc studies are reported which investigated the use of added damping layers at the base of a wind-tunnel model of a chimney as a means of increasing its overall structural damping. Significant increases in the logarithmic decrement were obtained from decaying free-vibration tests and in subsequent wind-tunnel tests corresponding decreases in windexcited tip response were measured.

It was concluded that the technique is promising for wind-tunnel parametric studies in which significant changes in the structural damping are required and recommends further work.
