BOSPHORUS BRIDGE SEISMIC VISCOUS DAMPER INSTALLATION

Bosphorus Bridge is one of the first suspension bridges in the world. At the time of its construction, mostly cross-suspension cables were used in this type of bridge throughout the world. However, with time, it has been found that vertical suspension cables are much more efficient in carrying bridges. 

Therefore, in the 40th Year of Maintenance of the Bosphorus Bridge, cables were replaced vertically. Because vertical cables are not taking a horizontal burden on the bridge, seismic viscous dampers were installed where the deck and tower legs approach each other. Nunteknik lifted these -2,5 ton- dampers to 60 mt height by platforms and installed dampers while the bridge was working.
