Load model for enhanced fatigue life estimation of Norwegian railway bridges: calibration, application, and uncertainties
(Doctoral theses at NTNU;2024:149, Doctoral thesis, 2024)The railway transportation is a crucial component of transportation infrastructure, known for its high capacity, environmental friendliness, and reliability. Despite requiring substantial initial investments, railway ... -
Load model of historic traffic for fatigue life estimation of Norwegian railway bridges
(Doctoral theses at NTNU;2019:73, Doctoral thesis, 2019)Material fatigue is the primary damage mechanism in steel railway bridges and ultimately causes material fracture and eventually component and system failure. It is essential that the infrastructure owner can predict and ... -
Loading rate effects on the fracture of Ni/Au nano-coated acrylic particles
(Journal article; Peer reviewed, 2012)Mechanical failure of monodisperse Ni/Au coated acrylic particles has been investigated by individual compression tests using nanoindentation-based technique equipped with a flat diamond punch. We have found that both ... -
Local Dynamics of Offshore Wind Turbine Jacket Sub-structures
(Master thesis, 2010)The scope of this thesis has been to investigate the existence of out-of-plane vibration of jacket sub-structures for offshore wind turbines. This is done by making the program code JAC (Jacket Analysis Code), which is ... -
Local electrical properties of thermally grown oxide films formed on duplex stainless steel surfaces
(Journal article, 2018)The local electrical properties of thermally grown oxide films formed on ferrite and austenite surfaces of duplex stainless steel at different temperatures were investigated by Current sensing atomic force microscopy, X-ray ... -
Long Span Network Arch Bridges in Timber
(Master thesis, 2016)For years, the reduction in greenhouse gas emissions have been a global goal, and in the recent years this has led to an increased focus on emissions from the construction industry as well. With timber being an ... -
Long-Span Brettstapel Roof Structures: A Parametric Design Approach
(Master thesis, 2021)Bakgrunn: Tre har økt i popularitet som et konstruksjonsmateriale de siste årene, på grunn av et økt fokus på klimaendringer og materialets status som miljøvennlig. I en tid hvor digitalisering gjennomsyrer byggebransjen ... -
Long-term extreme buffeting response investigations for longspan bridges considering uncertain turbulence parameters based on field measurements
(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
(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 ... -
Long-term extreme response analysis of a long-span pontoon bridge
(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 ... -
Long-term extreme response analysis of cable-supported bridges with floating pylons subjected to wind and wave loads
(Doctoral theses at NTNU;2018:229, Doctoral thesis, 2018)A suspension bridge with floating pylons is a possible solution to cross a fjord with a large width and great depth. This new concept is a combination of a slender suspension bridge and tension-leg platforms supporting the ... -
Long-term extreme response analysis of marine structures using inverse SORM
(Chapter; Peer reviewed, 2017)In this paper the first order reliability method (FORM) found in connection with structural reliability analysis is first used in an inverse manner to efficiently obtain an approximate solution of the full long-term extreme ... -
Long-term Influence of Concrete Surface and Crack Orientation on Self-healing and Ingress in Cracks – Field Observations
(Journal article; Peer reviewed, 2018)This paper presents results from investigations on the long-term influence of concrete surface and crack orientation on ingress in cracks. Five reinforced concrete structures from Norway exposed to either de-icing salts ... -
Long-term monitoring of wind field characteristics and dynamic response of a long-span suspension bridge in complex terrain
(Journal article; Peer reviewed, 2017)Long-term monitoring data of wind velocities and accelerations on the Hardanger Bridge are used to investigate the relationship between the wind-loading and response processes. The extensive measurement system consisting ... -
Long-term response of a curved floating bridge to inhomogeneous wind fields
(Peer reviewed; Journal article, 2023)A numerical model of a 5 km long curved floating bridge, planned for the Bjørnafjord, in Norway, is subjected to strong wind events with stationary mean properties that vary along the bridge axis. A Weather Research and ... -
Long-term stochastic extreme response analysis of floating bridges
(Journal article; Peer reviewed, 2017)For the assessment of extreme responses 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 ... -
