A novel joint for driven concrete geothermal energy pile foundations
(Peer reviewed; Journal article, 2024)Geothermal energy pile foundations are among the most common types of energy geostructures which provide both structural support and can be used as a source with ground source heat pumps for heating and cooling buildings. ... -
NTNU-SINTEF SolarNet: A solar irradiation monitoring network at high latitudes
(Peer reviewed; Journal article, 2023)This study presents a monitoring network for solar irradiation at high latitudes, called NTNU-SINTEF SolarNet. The network collects, with a time resolution ranging from seconds to hours, solar irradiance data, e.g. global ... -
NTNUs prognosemodell for konvensjonell tunneldrift - Vurdering av boring
(Master thesis, 2019)NTNUs prognosemodell for konvensjonell tunneldrift er et empiribasert verktøy for planlegging av utførelsesmetoder og for estimering av inndrift og kostnader ved bruk av boring og sprenging som drivemetode. Siste revisjon ... -
Nullalternativet som ingen vil ha, men ofte ender med å få
(Journal article; Peer reviewed, 2023)Hvorfor mange samfunnsøkonomiske analyser ender med anbefaling om milliardprosjekt, som senere blir lagt på is fordi det ble for dyrt. -
Nullalternativets rolle i konseptvalgutredninger
(Concept rapport;71, Report, 2023)Rapporten ser på håndteringen av null- og nullplussalternativene i konseptvalgutredninger (KVU). Vi finner at nullalternativet ofte ikke utredes som et valgbart alternativ, men kun tas med som sammenligningsgrunnlag. Videre ... -
Numerical Analyses of Creep Behaviour at the Ellingsrud Test Fill

Numerical Analysis of a Soil Tunnel with Jet Grouting
(Master thesis, 2022)Løsmassetunneler er et komplekst ingeniørproblem, og kan være utfordrende både å forstå og designe. Økt urbanisering i Norge, kombinert med at mange store byer er lokalisert ved løsmasseavsetninger og marin leire, medfører ... -
Numerical analysis of dynamic response of jacket structures subject to slamming forces by breaking waves
(Journal article; Peer reviewed, 2017)The present study numerically analyzed the dynamic behavior of 3D framed structures subject to impulsive slamming forces by violent breaking waves. The structures were modeled using multiple lumped masses for the vertical ... -
Numerical Analysis of Wave Transmission behind Floating Breakwaters
(Master thesis, 2013)Floating breakwaters (FBs) have been widely used as an alternative solution to protect coastal sites especially small harbors and certain areas which are not suitable for rubble mound breakwaters. Floating breakwater cannot ... -
Numerical and Analytical Analysis of Geogrid Reinforced Soil Wall Subjected to Dynamic Loading
(Master thesis, 2012)The potential human and economic loss due to structural collapse of geo-synthetic reinforced soil walls during earthquakes us huge. This substantiates the need for reliable design of such structures. The focus of this study ... -
Numerical and experimental investigation of floating structures in regular waves
(Chapter, 2019)In this paper, an experimental and numerical study of a floating object is presented. The incorporation of both experimental and numerical tools for the investigation of a simple floating object provides the opportunity ... -
Numerical Framework for Modeling Cyclic Degradation of Soils
(Master thesis, 2017)For many years fatigue in soils has been a major design challenge. Due to cyclic loading the material behavior changes and permanent deformations are observed. Although explicit cyclic calculation methods exists, none are ... -
A numerical framework for modelling the dynamics of open ocean aquaculture structures in viscous fluids
(Peer reviewed; Journal article, 2020)This paper presents a complete numerical framework for modelling open ocean aquaculture structures in waves and current using Computational Fluid Dynamics (CFD). A structural dynamics model is incorporated to account for ... -
A numerical geotechnical model for computing soil slides at banks of water reservoirs
(Peer reviewed; Journal article, 2020)Soil slides can occur when the water level in a lake or a reservoir is lowered. This may take place in situations when a reservoir is flushed to remove sediments. The current study describes a three-dimensional numerical ... -
Numerical Investigation and Optimization of a District-Scale Groundwater Heat Pump System
(Peer reviewed; Journal article, 2023)Groundwater heat pump (GWHP) systems are acknowledged as renewable and sustainable energy sources that can effectively fulfill the heating and cooling requirements of buildings on a district level. These systems harness ... -
Numerical investigation into the effects of corrosion on the shear performance of pretensioned bridge girders with cast-in-place slabs
(Peer reviewed; Journal article, 2022)Corrosion and shear cracking are frequently observed near supports of pretensioned bridge girders in coastal climates, so non-linear finite element analysis was used to study the effect of corrosion on shear performance ... -
Numerical Investigation of a Post-tensioned Flat Slab with Steel Fibre Reinforcement
(Master thesis, 2013)This study consists of a numerical investigation of a post-tensioned flat slab without conventional longitudinal reinforcement; only steel fibres were employed to ensure sufficient ductility and shear capacity of the slab. ... -
Numerical Investigation of Focused Waves and their Interaction with a Vertical Cylinder using REEF3D
(Journal article; Peer reviewed, 2017)For the stability of offshore structures, such as offshore wind foundations, extreme wave conditions need to be taken into account. Waves from extreme events are critical from the design perspective. In a numerical wave ... -
