| Abstract: | In order to assess the effects of tuned mass dampers (TMDs) on wind actions, an aeroelastic model with a scale of 1:60 was constructed. Tests were performed in an atmospheric boundary layer wind tunnel to investigate the buffeting response of the pylon with a TMD fixed by a wire rope instead of a spring. The model was tested under different levels of damping. The experimental and numerical results showed that with the TMD in the optimal condition, the buffeting response was reduced by 47%. |
