Abstract

A series of wind tunnel model tests and theoretical analyses were conducted to investigate torsion excitation, response and vibration suppression of wind-excited buildings. An aeroelastic model for pure torsion vibration was developed and the aeroelastic test results were compared with those obtained by other wind tunnel test techniques. The comparison and practice indicated that this type of modelling technique can be a convenient and efficient way to explore the mechanisms of torsional excitation and predict the torsional response of tall buildings to wind after considering mode shape correction. It is also shown that tuned mass dampers were effective in suppressing the torsional vibration of the building if the parameters of the tuned mass damper were properly selected.
