Abstract: |
A multi-span suspension bridge on floating supports has been evaluated and found to be a suitable option for the crossing of Bjørnafjorden on the West Coast of Norway. The proposed concept combines known technologies such a multi-span suspension system, floating supports inspired by the tension-leg platforms technology commonly used in the offshore industry and a top cable connecting the top of the four pylons. Such a construction would pioneer the field of strait crossings at extreme depths for which conventional bridges are not suitable. The absence of similar constructions and therefore the lack of references constitute significant challenges for the design group. The present article describes the global behaviour of the structure under normal operating conditions and summarizes the main findings from the investigations carried out in the initial study phases. |
