RESPONSE OF FLEXIBLE STRUCTURES WITH TUNED MASS DAMPERS ACTED BY WIND

Different types of structures like chimneys, high rise buildings or large openings floors can be considered as vibration sensitive structures. Beside classical measures applied to decrease the vibration sensitivity, a modern solution to control those vibrations is to endow the structure with special damping devices. This category of special devices can include tuned mass dampers, individually designed for every type of structure. Beside the theoretical background on TMD and wind loads on structures, the paper shows the response of a high rise chimney with TMD, acted by wind. The structure response is obtained from different analyses in time and frequency domain.
