    • Aerodynamic study of a suspension bridge deck by CFD simulations, wind tunnel tests and full-scale observations 

      Kusano, Ibuki; Cheynet, Etienne; Jakobsen, Jasna Bogunovic; Snæbjörnsson, Jonas Thor (Journal article; Peer reviewed, 2021)
      Assessing the aerodynamic characteristics of long-span bridges is fundamental for their design. Depending on the terrain complexity and local wind conditions, episodes of large angles of attack (AoA) of 15° may be observed. ...

    • Assessment of wind conditions at a fjord inlet by complementary use of sonic anemometers and lidars 

      Jakobsen, Jasna Bogunovic; Cheynet, Etienne; Snæbjörnsson, Jonas Thor; Mikkelsen, Torben; Sjøholm, Mikael; Angelou, Nicolas; Hansen, Per; Mann, Jakob; Svardal, Benny; Kumer, Valerie-Marie; Reuder, Joachim (Peer reviewed; Journal article, 2015-12-02)
      Wind velocity measurement devices based on the remote optical sensing, lidars, are extensively applied in wind energy research and wind farm operation. The present paper demonstrates the relevance and potential of lidar ...

    • Dual lidar wind measurements along an upstream horizontal line perpendicular to a suspension bridge 

      Nafisifard, Mohammad; Jakobsen, Jasna Bogunovic; Cheynet, Etienne; Snæbjörnsson, Jonas Thor; Sjöholm, Mikael; Mikkelsen, Torben (Journal article; Peer reviewed, 2021)
      Remote wind sensing can complement traditional anemometry at a bridge site and contribute to an improved wind-resistant design of long-span bridges. This study examines wind lidar measurement data recorded along a ...

    • Improved long-span bridge modeling using data-driven identification of vehicle-induced vibrations 

      Cheynet, Etienne; Daniotti, Nicolo; Jakobsen, Jasna Bogunovic; Snæbjörnsson, Jonas Thor (Journal article; Peer reviewed, 2020)
      The paper introduces a procedure to automatically identify key vehicle characteristics from vibrations data collected on a suspension bridge. The primary goal is to apply a model of the dynamic displacement response of a ...

    • The influence of terrain on the mean wind flow characteristics in a fjord 

      Cheynet, Etienne; Liu, Shengnan; Ong, Muk Chen; Jakobsen, Jasna Bogunovic; Snæbjörnsson, Jonas Thor; Gatin, Inno (Journal article; Peer reviewed, 2020)
      Flow conditions in complex terrains such as fjords are highly three-dimensional and thus not properly captured by the wind flow models developed for homogenous terrains. In the present study, we explore the potential of ...
