Abstract:Wind tunnel tests on a steel angle transmission tower with a aeroelastic model under typhoon wind field and terrain B wind field were carried out, and then the time series of wind velocity for different height of the transmission tower were simulated by WAWS method and the wind-induced responses were calculated with FEM in time domain. The comparison of wind-induced response and wind vibration factor are conducted. The results indicate that: The aerodynamic damping is larger and can't be ignored. The wind-induced acceleration responses enlarge significantly with wind velocity increase, the wind-induced acceleration response under typhoon wind field is more intensity than that under terrain B wind field, and the amplification is up to 20%~30% . The highly weighted wind vibration factor with value of 1.59 under terrain B wind field, and the value of 1.85 are found under typhoon wind field, the amplification is up to 16% in total. The results from numerical simulation are in good agreement with that from the wind tunnel test. Therefore, the design of transmission tower in typhoon-prone areas should take the fluctuating wind load magnification effect into consideration.
