Damage Detection Applied to a Full-Scale Steel Bridge Using Temporal Momens
Svendsen, Bjørn Thomas; Frøseth, Gunnstein Thomas; Rønnquist, Anders (Peer reviewed; Journal article, 2020)The most common damages in existing highway and railway steel bridges are related to fatigue and are, as reported in the literature, found in the structural system of the bridge deck. This paper proposes a methodology for ... -
Damage Identification of Structures with Accelerometers Under Idealized Conditions
Fjelldal, Jens Roar; Kjøle, Agnethe Maria (Master thesis, 2020)Dagens vei og jernbanenett består av et stort antall bruer som enten nærmer seg eller har overskredet levetiden som ble lagt til grunn for dimensjonering av disse konstruksjonene. Det er ikke økonomisk å erstatte disse ... -

A data-based structural health monitoring approach for damage detection in steel bridges using experimental data
Svendsen, Bjørn Thomas; Frøseth, Gunnstein Thomas; Øiseth, Ole Andre; Rønnquist, Anders (Journal article; Peer reviewed, 2022)There is a need for reliable structural health monitoring (SHM) systems that can detect local and global structural damage in existing steel bridges. In this paper, a data-based SHM approach for damage detection in steel ... -
Improved finite element model updating of a full-scale steel bridge using sensitivity analysis
Svendsen, Bjørn Thomas; Petersen, Øyvind Wiig; Frøseth, Gunnstein Thomas; Rønnquist, Anders (Journal article; Peer reviewed, 2021)There are many uncertainties related to existing bridges that are approaching or have exceeded their original design life. Lifetime extension analysis of bridges should be based on validated numerical models that can be ... -
Modal Analysis and Damage Identification of the Hell Bridge Test Arena
Granhaug, Edvart Braathen; Pontseele, Leander Anton Guust Van de (Master thesis, 2018)The purpose of the Hell Bridge test arena is to assess new sensor technology, monitoring algorithms and SHM techniques on a real structure in a controlled environment to establish reliable, cost-effective and time efficient ... -
Operational modal analysis and finite element model updating of the Brattøra Bridge
Reppen, Bjørnar Andenes; Sandrib, Nora Sofie (Master thesis, 2024)I denne masteroppgaven utføres dynamiske målinger på Brattørbrua i Trondheim ved bruk av en metode der sensorene systematisk flyttes på i ulike oppsett. Broen er en rullebro med to skjærlåser i midtspennet som holder de ... -
