| Abstract: | Fluctuating wind load of each floor of the steel tower was simulated based on the resonance wave method. The steel tower structure is simplified as two-dimensional lumped mass model. Then, the wind-induced vibration response of the steel tower was calculated based on the transient dynamic module of ANSYS and the technical parameters of vibration control were provided. |
