Snijder, H.H. Publication year 2013 Abstract The 'Hovenring' is a bicycle roundabout flyover built as a signature bridge with a central steel pylon carrying a circular bridge deck suspended through stay-cables. Shortly after installation of the bridge, the stay-cables turned out to vibrate in the wind due to vortex shedding. These vibrations have possibly caused fatigue damage in the threaded rods of the cable anchorages. Therefore, fatigue assessment were made using both traditional S-N-curves (Wöhler curves) in combination with the Palmgren-Miner damage accumulation rule as well as fracture mechanics analyses using crack growth data. The design fatigue life of the threaded rods appeared to be extremely short and therefore it was decided to replace them. This paper shows that is a dangerous design procedure to deliberately not consider vortex shedding and possible fatigue damage in the design stage an to take measures against vortex shedding only after completion of a bridge structure Subject Building Engineering & Civil EngineeringSR - Structural ReliabilityTS - Technical SciencesBuildings and InfrastructureArchitecture and BuildingBuilt EnvironmentFatigueStay-cablesThreaded rodCable anchorageVortex sheddingFracture mechanicsBridgeFlyover To reference this document use: http://resolver.tudelft.nl/uuid:acd17ea5-79c6-4586-b847-8080cd5c8476 TNO identifier 479582 Publisher IABSE International Association for Bridge and Structural Engineering Source IABSE Symposium Kolkata 2013.
