Preferred solution, K12 – Appendix I Fatigue analyses
This report describes the work performed in consideration of fatigue capacity of the selected concept (K12) in the concept development work of a floating bridge over Bjørnafjorden. Fatigue calculations have been performed for selected details in the bridge girder, the connection between columns and bridge girder/pontoons, mooring chains and stay cables. Large parts of the assessed structures have an acceptable fatigue utilization. However, some details are found to have insufficient fatigue life and need additional measures.
