| Abstract: |
The paper presents key aspects in the design of concrete structures for Norway’s largest on-shore infrastructure project, the new motorway E18 between Grimstad and Kristiansand. The DBFO project includes 38.5 km of four lane motorway along Norway’s southern coast, a considerable amount of secondary roads, 12 km of tunnels and some 60 bridges – realized between 2006 and 2009. The bridges have to meet highest demands regarding robustness, durability and low maintenance in rough environmental conditions. To achieve this, bridges were primarily designed as semi-integral structures thus minimizing the number of bearings and joints. The paper highlights the design approach for bridge structures. The basic principles are explained on the basis of built examples |
