    • Wind-Induced Response of Long-Span Suspension Bridges Subjected to Span-Wise Non-Uniform Winds: A Case Study 

      Forbord, Erlend Munkeby; Hjellvik, Hallvard (Master thesis, 2017)
      The Hardanger Bridge has a main span of 1 310 meters which makes it the longest suspension bridge in Norway and among the top 15 longest in the world as of 2017. The bridge consists of only two traffic lanes and one ...

    • Wind-wave directional effects on fatigue of bottom-fixed offshore wind turbine 

      Sørum, Stian Høegh; Krokstad, Jørgen R; Amdahl, Jørgen (Journal article; Peer reviewed, 2019)
      The current trend for offshore wind energy is that larger turbines are placed on monopile foundations at increasing water depth. This requires larger foundations, increasing the importance of hydrodynamic loading. It is ...
