The UHV double column suspended guyed tower is a typical wind-sensitive structure,which is susceptible to different degrees of damage and destruction under different wind loads.The relevant research on wind-induced damage assessment of such structures is urgently needed.Therefore,a wind disaster fragility analysis method considering multiple performance levels of UHV double column suspended guyed tower is proposed in this paper.First,the wind tunnel test of the rigid model of the structural column is carried out,and the aerodynamic three-component force coefficient of the column is obtained.Furthermore,the corresponding wind load is simulated.Then,the performance level of the double column suspended guyed tower is qualitatively divided,and the corresponding quantitative model of each performance level is given based on Pushover analysis.Finally,based on the probabilistic wind disaster demand model of double column suspended guyed tower,the wind disaster fragility analysis is carried out,and the influence of wind direction angle on the fragility curve is studied.The results show that:the aerodynamic lift coefficient CL and aerodynamic moment coefficient CM of the main column of the structure are close to 0 at different wind angles,while the aerodynamic drag coefficient CD is greater than 2,and it shows an increasing trend from 0° to 45°.Based on the vertex displacement of the column,multiple performance levels of double column suspended guyed tower can be established.According to the analysis of wind disaster fragility curve,the probability of wind damage and destruction of the double column suspended guyed tower under normal use conditions is small,and the structure has good wind resistance.Wind direction has a significant effect on the structural wind disaster fragility curve.The most unfavorable and favorable wind angles of double column suspended guyed tower are 90° and 0°,respectively.
