Evaluating cable forces in cable supported bridges using ambient vibration method
2006 (English)In: The International Conference on Bridge Engineering – Challenges in the 21st Century , November 1-3, 2006, Hong Kong, Hong Kong, 2006Conference paper (Other academic)
This paper deals with the assessment of cable forces in existing cable supported bridges using the ambient vibration method. A case study of the Älvsborg suspension bridge in Sweden is presented. Dynamic measurements of the backstays and hangers as well as on each strand in one of the splay chambers have been carried out. The measured frequencies are evaluated and calculations of corresponding axial force in the cable structures are performed taking into account the cable sag, boundary conditions and flexural rigidity. Modal analyses have been used to study the shape of vibration and for comparison with finite element models.
