Cable vibrations at Dubrovnik Bridge
The only cable stayed bridge in Croatia, the Dubrovnik bridge, was opened for traffic in 2002. The main cable stayed bridge with composite superstructure is jointed in span to the prestressed concrete approach bridge by a hinge type connection. The bridge has experienced vibrations of cable stays under certain wind conditions, as with many other cable stayed bridges around the world. After a short review of results of wind tunnel tests and various numerical analyses, field observations of cable stay vibrations are highlighted. Only after extremely violent movements of cable stays and the superstructure under heavy damp snow storm occurred, resulting in substantial damage, was it decided to apply vibration mitigation measures. Adjustable cable dampers, based on latest MR technology were installed on the bridge to raise low structural damping of mostly affected cable stays. stays to continuously monitor their motion.
