Paper Abstract

Wind induced structural vibration of mast and tower structures on top of tall buildings can generate structural fatigue of the masts ad transmit vibration into the building. A method of reducing these vibrations is by installing a vibration absorber into the top of the mast. An experimental investigation into the use of cylinder-cup vibration absorbers for reducing motions of two model masts is reported in this paper. Test data include coefficients of friction, damping ratios and several dimensionless groups associated with vibration. These absorbers can be used successfully to reduce mast vibrations when properly scaled.
