Cylindrical cavity expansion approximations using different constitutive models for the target material
(Journal article; Peer reviewed, 2017)In this article, we investigate the results obtained using different constitutive models for the solution of the cylindrical cavity expansion problem under plane strain conditions. The cylindrical cavity expansion solutions ... -
D-regioner i betongbruer
(Master thesis, 2015)Denne masteroppgaven omhandler D-regioner i betongbruer. Rapporten fokuserer spesielt på bruk av stavmodellen i bruksgrensetilstand. Det er gjennomført et litteraturstudium av stavmodellen og beregninger for seks ulike ... -
D-regioner i betongbruer - dimensjonering av områder med konsentrerte laster
(Master thesis, 2015)I armerte betongkonstruksjoner kan det oppstå områder med ikke-lineære variasjon av tøyninger og brå spenningsvariasjoner. Disse områdene dimensjoneres ofte ved hjelp av stavmodeller, med trykkstaver i betong og strekkstaver ... -
D-regioner i betongkonstruksjoner
(Master thesis, 2016)I konstruksjoner hvor det skjer plutselige endringer i tverrsnitt eller lastpåføring oppstår det diskontinuerlige spenningsstrømmer. Med diskontinuerlig menes en spenningsfordeling som ikke kan analyseres med bjelketeori. ... -

(Research report, 2019)The report gives an overview of requirements and recommendations to frost durable concrete in standards and specifications, available to the author from a limited selection of standardization and engineering organizations ... -
Damage and Failure in an X65 Steel Pipeline Caused by Trawl Gear Impact
(Chapter, 2013)Offshore pipelines subjected to accidental impact loads from trawl gear or anchors may experience large global deformations and large local strains, creating a complex stress and strain history. In this study experiments ... -
Damage Detection Applied to a Full-Scale Steel Bridge Using Temporal Momens
(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 detection in structures using subspace identification
(Master thesis, 2021)Alle konstruksjoner blir utsatt for skader, og konsekvensene kan være fatale. Hvis en skade blir oppdaget før konstruksjonen når brudd kan nødvendige tiltak iverksettes for å forhindre kollaps og øke sikkerheten for ... -

Damage Identification of Structures with Accelerometers Under Idealized Conditions
(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 ... -

Damping in Timber Structures
(Doctoral Theses at NTNU, 1503-8181; 2012:263, Doctoral thesis, 2012)Key point to development of environmentally friendly timber structures, appropriate to urban ways of living, is the development of high-rise timber buildings. Comfort properties are nowadays one of the main limitations to ... -
Data on residual stresses of mooring chains measured by neutron diffraction and hole drilling techniques
(Peer reviewed; Journal article, 2020)Residual stresses in large offshore mooring chains have been measured for the first time and presented in this article. Two chain links with the same size and material, one only subjected to proof load and no cyclic service ... -
Data Set from Long-Term Wave, Wind, and Response Monitoring of the Bergsøysund Bridge
(Peer reviewed; Journal article, 2023)Wind, wave, displacement, and acceleration data have been collected in a measurement campaign on Norway’s Bergsøysund Bridge, an end-supported pontoon bridge, between the years 2014 and 2018. The data set is now available ... -
A data-based structural health monitoring approach for damage detection in steel bridges using experimental data
(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 ... -
Data-driven prediction of mean wind turbulence from topographic data
(Peer reviewed; Journal article, 2021)This study presents a data-driven model to predict mean turbulence intensities at desired generic locations, for all wind directions. The model, a multilayer perceptron, requires only information about the local topography ... -
Dataset for long-term wind and acceleration monitoring of the Hardanger Bridge
(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 ... -
Debonding length in normal concrete and fiber reinforced concrete
(Master thesis, 2016)In this thesis work an investigation program on normal plain reinforced beams (NC) and fibre reinforced concrete (FRC) was performed. In the first part of the study several ways of investigation of the internal cracking ... -
Deep autoencoder architecture for bridge damage assessment using responses from several vehicles
(Peer reviewed; Journal article, 2021)Vehicle-assisted monitoring is a promising alternative for rapid and low-cost bridge health monitoring compared to direct instrumentation of bridges. In recent years, centralized management systems for fleets of heavy ... -
Deep Learning analysis of the LV myocardium in CCTA for identification of patients with significant coronary artery stenosis
(Master thesis, 2021)For pasienter med innsnevring av moderat alvorlighetsgrad i koronararteriene må betydningen av innsnevringen defineres. I klinisk praksis gjøres dette vanligvis gjennom å måle FFR (Fractional Flow Reserve). I denne prosedyren ...
