Aerodynamic Effect of Non-uniform Wind Profiles for Long-Span Bridges
Lystad, Tor Martin; Fenerci, Aksel; Øiseth, Ole Andre (Chapter, 2019)Long-span bridges are often designed based on the assumption of wind field homogeneity. At the Hardanger Bridge, the wind field along the bridge span is monitored though 8 triaxial ultrasonic anemometers. Simultaneously ... -
Buffeting response of long-span bridges considering uncertain turbulence parameters using the environmental contour method
Lystad, Tor Martin; Fenerci, Aksel; Øiseth, Ole Andre (Peer reviewed; Journal article, 2020)Full-scale monitoring of the Hardanger Bridge has revealed significant turbulence-induced variability in the measured acceleration response. In this paper, a probabilistic model is used to describe the uncertain turbulence ... -
Estimation of Fatigue Damage due to Buffeting of Suspension Bridges
Anfinsen, Håvard Hatling; Waaler, Mads Kristoffer (Master thesis, 2021)I løpet av de siste 50 årene har mange frekvensbaserte metoder for å estimere utmattingsskader blitt presentert. Hovedmålet med denne avhandlingen er å sammenligne noen av de mest populære frekvensbaserte metodene mot ... -

Evaluation of mast measurements and wind tunnel terrain models to describe spatially variable wind field characteristics for long-span bridge design
Lystad, Tor Martin; Fenerci, Aksel; Øiseth, Ole (Journal article; Peer reviewed, 2018)The quality of the information about the wind field characteristics is crucial for accurately predicting the structural response of a long-span bridge subjected to dynamic wind loads. In this paper, in situ mast measurements ... -
Instrumentering av Bergsøysundbrua og Gjemnesundbrua
Dahlen, Adrian; Lystad, Tor Martin (Master thesis, 2013)Gjemnessundbrua og Bergsøysundbrua på Europavei E39 i Møre og Romsdal, skal instrumenteres for identifikasjon av strukturelle og dynamiske egenskaper. Denne rapporten omhandler dokumentasjon og beskrivelse av det utførte ... -
Long-term extreme buffeting response investigations for longspan bridges considering uncertain turbulence parameters based on field measurements
Lystad, Tor Martin (Doctoral theses at NTNU;2021:216, Doctoral thesis, 2021)When bridges become increasingly longer, the dynamic behavior from wind and waves can dominate the structural load effects. To build better knowledge about the dynamic behavior of long-span bridges subjected to turbulent ... -
Long-term extreme buffeting response of cable-supported bridges with uncertain turbulence parameters
Lystad, Tor Martin; Fenerci, Aksel; Øiseth, Ole Andre (Peer reviewed; Journal article, 2021)Although the full long-term method (FLM) is recognized as the appropriate way to identify the design stresses of marine structures subjected to stochastic environmental loading, the FLM has not yet been adopted for the ... -
Wind-Induced Response of Long-Span Suspension Bridges Subjected to Span-Wise Non-Uniform Winds: A Case Study
Forbord, Erlend Munkeby; Hjellvik, Hallvard (Master thesis, 2017)The Hardanger Bridge has a main span of 1 310 meters which makes it the longest suspension bridge in Norway and among the top 15 longest in the world as of 2017. The bridge consists of only two traffic lanes and one ...
