| Summary: | Optimisation of steel structures is an important part in the goal of reducing the CO2 footprint. The new 260 m long bridges for approach light are an example of optimisation of the structure compared with the design by KAIR the owner of Nuuk Airport, Greenland. In the new design several other advantages for the project have been included and architects have been involved, since the bridges have a significant visual impact seen from Nuuk city. The runway is being extended. Due to limited space two steel bridges are built to support the approach lights and to have an easy access during maintenance. Each of the two bridges consists of four lattice towers. A walkway and the lights will be positioned on top of the bridge lattice. The length of the bridge is 260 m, and the height of the towers varies between 25-65 m.In Greenland the wind and ice load are predominant, and it is therefore vital to reduce wind drag on tall and slender structures. Consequently, circular tubes are used instead of angle profiles. All ... |
