Influence of wind angle of attack and isotropic turbulence on wind-induced vibrations of ice-accreted bridge cables
Original language description
Bridge-supporting cables and mast guys with high flexibility and low damping often experience vibrations with large amplitudes that may have consequently destructive effects on supported structures. Surface roughness and ice accretion are important issues, as they can considerably alter aerodynamic characteristics of bridge cables. This study describes wind-tunnel experiments on vortex-induced vibration of cylindrical section models with the deliberately adjusted natural frequency f = 5 Hz. The range of reduced velocity was Vr 2 h3:90 7:77i that corresponds to the resonance band of St 2 h0:14 0:25i. Three different cable models were used, i.e., smooth cylinder representing dry cable, helical strand cable and cable with ice-accretion. The isotropic turbulent flow was modelled to represent the low turbulent and moderately turbulent wind conditions.
