Field observation of the full-scale wind-induced cable vibration

Wind-Induced Coupling Vibration Effects of High-Voltage Transmission Tower-Line Systems

“…Using aeroelastic wind tunnel models, the experimental studies have focused on the wind-induced response characteristics of tower-line coupling systems [13][14][15][16][17][18][19], aerodynamic damping of wires [20], dynamic tension of ice-covered wires [21], and wind-induced responses in ice-covered line structures [22][23][24][25][26]. Researchers have also conducted field dynamic measurement studies of transmission line structure [27][28][29][30][31][32], but due to field test conditions, the existing field tests have mostly focused on the dynamic characteristics of transmission tower structure [27][28][29][30]. The existing field measurement studies regarding wind-induced responses of tower-line coupling systems are still insufficient.…”

An experimental investigation on vortex induced vibration of a flexible inclined cable under a shear flow

“…The key components of these long-span bridges, stayed cables, easily behave in multi-mode VIVs while in this non-uniform flow, i.e., the velocity profile in the atmospheric boundary layer (Main and Jones, 1999;Matsumoto et al, 2003;Zuo et al, 2008;Zuo and Jones, 2010;Chen et al, 2011Chen et al, , 2013. Zuo et al (2008) and Zuo and Jones (2010) performed full-scale measurement investigations on the Fred Hartman Bridge in Houston (Texas, USA) and observed VIVs of cables with sixth and seventh modes or with fifth and sixth modes, respectively.…”

An ultrasonic transmission thickness measurement system for study of water rivulets characteristics of stay cables suffering from wind–rain-induced vibration

“…This phenomenon is a large amplitude vibration (upto 2 m) of the inclined stay cable of the cable-stayed bridge, which may induce undue stresses and fatigue in the cables themselves and in the connections at the bridge deck and tower. Many studies have been carried out in the past two decades through field measurements [1][2][3][4], wind tunnel tests [1,[5][6][7][8][9][10][11][12][13][14] and theoretical analyses [15][16][17][18][19][20]. Although many studies have been done, the quantitative information of the water rivulets on cable surface, such as the thickness, width, shape and oscillation characteristics, has not been obtained; furthermore, the correlation between the rivulet oscillations and the RWIV of the cable should be clarified.…”
