    • Bridge aerodynamics in skew winds: Generalized buffeting load modelling and response analysis 

      Morais da Costa, Bernardo (PhD thesis UiS;, Doctoral thesis, 2022-11)
      This thesis deals with the modelling of wind loads on bridges. When turbulent wind blows past a bridge deck, the deck experiences fluctuating loads, i.e., buffeting loads. Most buffeting theories concern straight bridge ...

    • Bridge buffeting by skew winds: A revised theory 

      Morais da Costa, Bernardo; Wang, Jungao; Jakobsen, Jasna Bogunovic; Øiseth, Ole Andre; Snæbjørnsson, Jonas Thor (Peer reviewed; Journal article, 2021-01)
      An improved bridge buffeting theory is established with an emphasis on skew wind directions, for both turbulence- and motion-dependent forces. It provides simplifications and generalizations of previously established ...

    • Data-driven prediction of mean wind turbulence from topographic data 

      Morais da Costa, Bernardo; Snæbjørnsson, Jonas Thor; Øiseth, Ole Andre; Wang, Jungao; Jakobsen, Jasna Bogunovic (Peer reviewed; Journal article, 2021)
      This study presents a data-driven model to predict mean turbulence intensities at desired generic locations, for all wind directions. The model, a multilayer perceptron, requires only information about the local topography ...

    • Long-term response of a curved floating bridge to inhomogeneous wind fields 

      Morais da Costa, Bernardo; Wang, Jungao; Jakobsen, Jasna Bogunovic; Snæbjörnsson, Jonas Thor; Øiseth, Ole Andre (Peer reviewed; Journal article, 2023-07)
      A numerical model of a 5 km long curved floating bridge, planned for the Bjørnafjord, in Norway, is subjected to strong wind events with stationary mean properties that vary along the bridge axis. A Weather Research and ...
