In the past there have been attempts to control wind response of chimneys using strakes, perforated screens, rubber mountings, hanging chain dampers and tuned mass dampers. However, a systematic and detailed study on latest designed vibrationdampers at chimney top is not seen in literature. In the present paper, principle of the damping system is discussed. Mass and stiffness of the damper are calculated. Amplitude of the top of chimney during vortex shedding is calculated. Results thus obtained have been discussed. Some latest damping systems have also been presented for authenticity.
