Design of an experimental setup for measurements of the aerodynamic properties of bridge decks
Kaasa, Lars Halvor (Master thesis, 2012)As modern bridge design continuously aims for longer and slender bridges, it is necessary to be able to determine aerodynamic properties of such structures with a highdegree of accuracy. The horizontal degree of freedom ... -
Earthquake Induced Behavior of Submerged Floating Tunnels with Tension Leg Anchorage
Indridason, Birgir (Master thesis, 2013)SUMMARY:The purpose of this study is to examine the behavior of a submerged floating tunnel (SFT) anchored by tension legs and subjected to seismic excitation. A proposal of a tunnel crossing the Høgsfjord in Norway is ... -
Earthquake Response of Suspension Bridge Crossing the Sognefjord
Skogmo, Håkon Olav (Master thesis, 2013)SammendragDenne avhandlingen vurderer den foreslåtte byggingen av en hengebru i et spenn over Sognefjorden i lys av jordskjelv. Den foreslåtte broen har et spenn på 3700 meter og tårnene har en høyde på 455 meter. Om broen ... -
Full-scale investigation of the effects of wind turbulence characteristics on dynamic behavior of long-span cablesupported bridges in complex terrain
Fenerci, Aksel (Doctoral theses at NTNU;2018:100, Doctoral thesis, 2018)The global demand for long-span cable-supported bridges are emerging. Impressive number of projects have been realized in the last two decades and many more projects are in their planning, design or construction phases ... -
Modelling of the self-excited forces for bridge decks subjected to random motions: an experimental study
Siedziako, Bartosz (Doctoral theses at NTNU;NTNU, 2018:52, Doctoral thesis, 2018)This thesis concerns the dynamic behaviour and analysis of long-span bridges subjected to wind loading and, in particular, the modelling of self-excited forces based on wind tunnel measurements. The goal of this PhD study ... -
Modelling the stochastic dynamic behaviour of a pontoon bridge: A case study
Kvåle, Knut Andreas; Sigbjørnsson, Ragnar; Øiseth, Ole (Journal article; Peer reviewed, 2016)Herein, a study on the hydrodynamic modelling of pontoon bridges is presented, with the Bergsøysund Bridge as a representative example. The model relies on the finite element method and linearized potential theory. The ... -
Structural Dynamics of Subsea Structures in Earthquake Prone Regions
Bruun, Karianne (Master thesis, 2013)Med utviklingen som har funnet sted innenfor den norske oljebransjen de siste årene har både teknologien og utfordringene blitt mer komplekse. Subsea-operasjoner har blitt mer vanlig og gir utslag i at det på havbunnen i ...
