Wind disaster risk assessment of ultra high voltage(UHV) double-column suspended guyed tower is an important part of its performance-based wind resistance design. On this basis

this paper proposes a wind disaster risk assessment method for UHV double-column suspended guyed tower. First

the wind disaster risk assessment framework of double-column suspended guyed tower is introduced. Then

based on this framework

a wind hazard analysis is conducted for Hami

Xinjiang

followed by a wind disaster fragility assessment of the UHV double-column suspended guyed tower. Finally

based on the convolution of the wind hazard function and the fragility function

the wind disaster risk function of the structure is obtained

the annual failure probability of the structure under different performance levels is calculated

and the influence of wind direction on the structural wind hazard risk is discussed. The results show that the NE direction of wind direction in Hami

Xinjiang has the greatest wind hazard

while the S direction corresponds to the least risk of wind disaster. Attention should be paid to the structural damage in the NE direction. When the wind speed is less than 44 m/s

the probability of slight damage is very small under any wind direction

and the structure has strong wind resistance. The annual failure probability of the double-column suspension guyed tower under NE-90˚ and NE-0˚ conditions is maximum and minimum

respectively. The variation trend of annual failure probability is similar to the structural wind disaster fragility curve. The annual failure probability of the double-column suspended guyed tower under different wind combinations is small

and the wind damage and destruction of the structure is a small probability event.
