      Along the Coastal Highway E39 in the western coast of Norway, Norwegian Government is planning to build several extreme bridges spanning from 1.5 to 5 km. The region is typically mountainous with deep fjords seeping inland. ...
    • Wind forces on bridge decks using state-of-the-art FSI methods 

      Helgedagsrud, Tore Andreas (Doctoral theses at NTNU;2019:180, Doctoral thesis, 2019)
      Several bridges with span widths that challenge present technology are currently under planning in Norway, and wind effects are among the major concerns. Traditionally, wind-structure interactions are studied experimentally ...
    • Wind Induced Dynamic Response of Concrete Box Girders During a Balanced Cantilevered Construction Stage 

      Helliesen, Martine Øien (Master thesis, 2013)
