Load effects in reinforced concrete beam bridges affected by alkali–silica reaction—Constitutive modelling including expansion, cracking, creep and crushing
(Peer reviewed; Journal article, 2021)Material modelling, from the micro to the macro level, of concrete affected by alkali–silica reaction (ASR) has been devoted a lot of research. However, the application of the material models in structural analyses of ... -
Load effects of alkali-silica reaction in reinforced concrete beam bridges - Material testing, Constitutive modelling and Numerical simulation
(Doctoral theses at NTNU;2023:20, Doctoral thesis, 2023)Alkali-silica reaction (ASR) is a deterioration process in concrete that was discovered in the mid-1930s, and which still affects concrete structures all over the world. ASR is considered a multi-scale phenomenon; it is a ... -
Load Frequency-Based Power Management for Shipboard DC Hybrid Power Systems
(Peer reviewed; Journal article, 2020)The development of marine integrated power systems has enabled all-electric ship, with electric propulsion systems to be powered from diesel-generators. In addition, vessels with DC hybrid power sources such as fuel cell, ... -
Load measurements at riprap toe.
(Master thesis, 2018)Riprap is widely used as slope protection and when placed on the downstream slope of a rockfill dam, it provides erosion resistance under overflow conditions. For steep downstream slopes (S > 50%), initiation of riprap ... -
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 ... -
Load Modelling of Buildings in Mixed Energy Distribution Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:78, Doctoral thesis, 2007)The main topic of this thesis has been the development of a new method for load modelling of buildings in mixed energy distribution systems. The method estimates design load profiles, yearly load profiles, load duration ... -
Load transfer from coupled analysis to structural design of FWTs
(Master thesis, 2022)It is of research interest to establish a technique to capture the loads on the structural members of the offshore wind turbine when they are exposed to simultaneous wind and wave action. Unlike other floating offshore ... -
Loading and blade deflection of a tidal turbine in waves
(Journal article; Peer reviewed, 2019)A coupled numerical model has been developed and validated to study the fluid–structural interaction responses of a three-bladed tidal turbine in aligned waves and current. The unsteady blade element momentum (BEM) theory ... -
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 ... -
Loads on the Gravity-net-cage from Waves and Currents
(Master thesis, 2014)Due to limited space close to shore and environmental concerns, the trend has become to move the fish farms to more exposed areas. This motivates the study of loads on the fish farm in more energetic currents and waves.In ... -
Local and Global Properties of the Harmonic Polynomial Cell Method: In-depth Analysis in Two Dimensions
(Journal article, 2017)A detailed and systematic analysis is performed on the local and global properties of the recently developed Harmonic Polynomial Cell (HPC) method, a very accurate and efficient field solver for problems governed by the ... -
Local and global responses of a floating bridge under ship-girder collisions
(Journal article; Peer reviewed, 2018)The Norwegian Public Roads Administration is running a project “Ferry Free Coastal Route E39” to replace existing ferry crossings by bridges across eight fjords in western Norway. Since most of the fjords are wide and deep, ... -
Local and non-local drivers of consumption-based water use in China during 2007–2015: Perspective of metacoupling
(Peer reviewed; Journal article, 2022)Increasingly growing consumption-based water use (WU) combined with climate change have exacerbated water stress globally and regionally, yet little is known about how the WU change is affected by metacoupled processes ... -
