Assessment of the dynamic response of the Bergsøysund Bridge in the frequency domain
Kvåle, Knut Andreas (Master thesis, 2013)The Norwegian Public Roads Administration is currently both planning and building a new coastal highway, along the fjord-dense Norwegian west coast. In that concern, dynamic response of floating structures exposed to wave ... -
Covariance-driven stochastic subspace identification of an end-supported pontoon bridge under varying environmental conditions
Kvåle, Knut Andreas; Øiseth, Ole; Rønnquist, Anders (Journal article, 2017)The Bergsøysund Bridge is currently being extensively monitored with accelerometers, anemometers, wave radars and GNSS sensors. By applying Covariance-driven Stochastic Subspace Identification (Cov-SSI), the modal parameters ... -
Dataset for long-term wind and acceleration monitoring of the Hardanger Bridge
Fenerci, Aksel; Kvåle, Knut Andreas; Petersen, Øyvind Wiig; Rønnquist, Anders; Øiseth, Ole Andre (Peer reviewed; Journal article, 2021)A large data set of wind and acceleration data collected through long-term monitoring of the Hardanger Bridge in Norway is described in this data paper. The data set includes both raw data and organized data, and it is ... -
Dynamic behaviour of floating bridges exposed to wave excitation A numerical and experimental investigation
Kvåle, Knut Andreas (Doctoral theses at NTNU;2017:365, Doctoral thesis, 2017)By utilizing the buoyancy of the water in a crossing, floating bridges may provide permanent road links where other bridge types would be impossible or too costly to build. Still, floating bridges are not wide-spread in ... -
Dynamic Response of an End-Supported Pontoon Bridge due to Wave Excitation: Numerical Predictions versus Measurements
Kvåle, Knut Andreas; Øiseth, Ole Andre (Peer reviewed; Journal article, 2021)Herein, numerical predictions of the dynamic response of an existing floating pontoon bridge are compared with the measured dynamic response. Hydrodynamic coefficients that describe the fluid-structure interaction and the ... -
Effect of Stockbridge Dampers on the Vibration Response of Suspension Bridge Hangers
Solheim, Ingvild Mariannedatter (Master thesis, 2022)Vibrasjoner i hengestengene på Hålogalandsbrua forårsaket av virvelavløsning ble observert under byggingen av broen. Vibrasjonsdempere ble installert for å redusere amplituden til vibrasjonene, men flere av demperne ble ... -
Estimation of Long-Term Extreme Response of Floating Bridges
Tecle, Meron Tesfamariam; Tjugum, Tor Briseid (Master thesis, 2021)Ved beregning av langtids ekstremrespons for en gitt konstruksjon er som oftest metoden kalt Full Integrasjon anerkjent som den mest nøyaktige. Enkelte utfordringer kan likevel oppstå når komplekse konstruksjoner slik som ... -

Experiences from the five-year monitoring of a long-span pontoon bridge: What went right, what went wrong and what?s next?
Kvåle, Knut Andreas; Øiseth, Ole; Rønnquist, Anders (Journal article; Peer reviewed, 2019)The Bergsøysund Bridge is a 930-metre-long end-supported pontoon bridge located in Norway, and has been the target of a five-year-long, extensive monitoring program. Herein, we will describe the unique structural characteristics ... -
Hydrodynamic interaction of floating bridge pontoons and its effect on the bridge dynamic responses
Fenerci, Aksel; Kvåle, Knut Andreas; Xiang, Xu; Øiseth, Ole Andre (Peer reviewed; Journal article, 2022)As pontoons of floating bridges respond to the dynamic actions of the wind and wave loading, additional forces are imposed on the pontoons due to the hydrodynamic interaction of these floating bodies. The wave forces on a ... -
Kartlegging av vindindusert dynamisk oppførsel av Gjemnessundbrua
Karlsen, Øyvind Asbjørn (Master thesis, 2016)I forbindelse med prosjektet ferjefri E39, er Statens vegvesen interessert i samarbeid med parter der motivasjonen er relevant forskning til prosjektet. Derfor har Statens vegvesen og NTNU inngått en avtale hvor studentene ... -
Long-term extreme response analysis of a long-span pontoon bridge
Giske, Finn-Idar Grøtta; Kvåle, Knut Andreas; Leira, Bernt Johan; Øiseth, Ole (Journal article; Peer reviewed, 2018)For the assessment of extreme load effects needed in design of marine structures, a full long-term analysis is recognized as the most accurate approach. However, due to the very large number of structural response analyses ... -
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 ... -
Operational modal analysis of an end-supported pontoon bridge
Kvåle, Knut Andreas; Rønnquist, Anders; Øiseth, Ole (Journal article; Peer reviewed, 2017)A comprehensive monitoring system is installed and currently in operation on the Bergsøysund Bridge, an end-supported floating pontoon bridge, collecting data on accelerations, displacements, waves, and wind. Using ...
