    • Tension during parametric excitation in submerged vertical taut tethers 

      Cantero, Daniel; Rønnquist, Anders; Næss, Arvid (Journal article; Peer reviewed, 2017)
      The construction of a suspension bridge with floating pylons or a submerged floating tunnel requires the installation of a mooring system. The option of taut vertical tethers, similar to those used in tension-leg platforms, ...
    • Tension-loaded bolted connections in steel structures 

      Skavhaug, Elin Stensrud; Østhus, Svanhild Irene (Master thesis, 2015)
