Cable Stays Vibration Mitigation by Means of Viscous Dampers Attached to Adjacent Cables

In the case of cable-stayed bridges with very large spans of over 400m, the common engineering practice at the national level requires the placement of vibration mitigation devices in the form of external dampers (usually of the viscous type). The main disadvantage of this solution is due to the rel...

Description
Summary:In the case of cable-stayed bridges with very large spans of over 400m, the common engineering practice at the national level requires the placement of vibration mitigation devices in the form of external dampers (usually of the viscous type). The main disadvantage of this solution is due to the relative positions of these devices along the cable, which are very close to the edge, in a zone where their influence on the cable is minimal.
