Abstract:

Stay Cable Damping by Real-Time Controlled MR Dampers

Stay cables are prone to wind-induced vibrations due to their low inherent damping of 0,1%-0,15%. Since wind conditions vary over time, vibration amplitudes and frequencies are unknown. Consequently, cable damping systems must generate amplitude and frequency independent cable damping. It is described how this requirement can be fulfilled by real-time controlled magnetorheological dampers. The efficiency of the adaptive cable damping system is experimentally validated and its implementation on the world largest stay cable bridges, the Sutong Bridge in China and the Russky Bridge in Russia, is described.
