| Abstract: | A research of the buffeting response of two types of steel antennas at the top of a super-high rise building is presented in the paper.The two types of aeroelastic antenna models were first tested in a wind tunnel and numerical computations were made to theoretically and experimentally investigate the buffeting responses of the antennas.A structural improvement measure for the second type of antenna model was proposed and the model was then tested.the whiplash effect of the second type of antenna was finally numerically analysed.The numerical and experimental results provide the reliable basis for the analysis and design of the structure. |
