| Abstract: | The simulation of fluctuating wind load acting on Hefei TV Tower and the wind induced vibration response analysis are presented in this paper.The matrix of power spectral density function of fluctuating wind load is established first.With the spectral representation method,19 samples of fluctuating wind load are simulated considering the vertical co relation.Then, the wind induced vibration response of the tower is calculated. |
