| Abstract: |
The New Varodd Bridge is a 655m concrete girder bridge with four main spans with a maximum length of 260m. The bridge will be located in a very narrow position between the existing Varodd suspension bridge on the southern side and the existing Varodd girder bridge on the northern side. The new bridge will be constructed as a balanced cantilever with a connection to the existing girder bridge that connects the bridges in transverse displacements but not in vertical displacements. During this phase the bridge is very sensitive to wind effects. An additional complication lies in the proximity of the existing bridges which highly impact the flow around the new structure. This paper addresses the coverage of these aspects, through a combination of wind response calculations in both frequency domain and time domain, as well as wind tunnel tests performed on a 1:160 scale aeroelastic model of the balanced cantilever. |
