REDWIN – REDucing cost in offshore WINd by integrated structural and geotechnical design
(Journal article; Peer reviewed, 2018)The cost of offshore wind energy production has to be reduced continuously to improve its competitiveness compared to other energy sources. To contribute to this goal, a 4- year research project REDWIN – REDucing cost of ... -
Rehabilitation of Cableway posts, Longyearbyen
(Master thesis, 2022)Taubanebukkene formidler byens gruvehistorie og er kategorisert som kulturminner. Grunnet varmere klima vil temperaturene i bakken øke og det aktive laget nå dypere. Dette fører til økte setninger og deformasjoner når ... -
Reinforcement corrosion in carbonated fly ash concrete
(Doctoral theses at NTNU;2018:230, Doctoral thesis, 2018)The cement industry contributes about 8% of the anthropogenic CO2 emissions, partly due to large consumption of cement and the emissions associated with the production (for Portland cement (PC) approximately 800 kg/t). One ... -
The relation between grain boundary precipitate formation and adjacent grain orientations in Al-Mg-Si(-Cu) alloys
(Peer reviewed; Journal article, 2021)The occurrence of grain boundary precipitates was investigated with respect to the crystallographic orientation of the adjacent grains in extruded AA6110, AA6063 and AA6061 alloys brought to T6 temper. It was found that ... -
Relative humidity measurements in concrete
(Master thesis, 2017)A commonly used way to monitor the concrete s moisture condition is to measure Relative humidity (RH). Measuring relative RH in concrete, and understanding the underlying mechanisms are complex tasks. Field measurements ... -
Reliability Analysis of Reinforced Concrete using Non-Linear Finite Element Analysis
(Master thesis, 2016)The purpose of the thesis is to investigate methods that may be used for assessing the reliability in large concrete structures in combination with non-linear nite element analyses (NLFEA). Reliability methods are applied ... -
Reliability Assessment of Long Span Suspension Bridges Subjected to Dead Loads
(Master thesis, 2016)In the present study the influence of standardized safety factors in large and heavy structures, where the major loading arises from self-weight of the structure itself, is considered. For this purpose, a reliability ... -
Reliability assessments of concrete structures using non-linear finite element analyses
(Master thesis, 2017)Reliability assessment of slender concrete columns using Non-linear finite element analysis (NLFEA) is studied in this thesis. Several reliability methods in combination with NLFEA are applied and discussed to assess the ... -
Repeatability in a multiphase pipe flow case study
(Peer reviewed; Journal article, 2021)A high degree of repeatability is most often an underlying assumption for research and development based on multiphase flow experiments. In this paper repeatability in multiphase flow experiments are studied through an ... -
Requirements and recommendations to frost durable concrete – an overview
(Chapter, 2019)Requirements and recommendations for frost durable concrete from standards and specifications from Europe, North-America and Asia, various international organizations and construction projects are reviewed, compared and ... -
Residual stresses and dimensional deviation in metal additive manufacturing: prediction and mitigation methods
(Doctoral theses at NTNU;2020:411, Doctoral thesis, 2020)Additive manufacturing (AM) has attracted wide attention over the past years due to its various advantages, such as design freedom, less production cost, and short production cycles. However, residual stresses and dimensional ... -
Resistance Analysis of Spherical Metal Thin Films Combining Van Der Pauw and Electromechanical Nanoindentation Methods
(Journal article; Peer reviewed, 2018)Although micron-sized metal-coated polymer particles are an important conductive filler material in anisotropic conductive adhesives, the resistance of the particles in adhesive is not well understood. In this study, a van ... -
Resistance measurements of high resistance concrete
(Master thesis, 2015)The importance of concrete resistivity in durability and service life aspects is widely recognized. Within this project, different measurement approaches were evaluated, with associated limitations and advantages. The ... -
Respons i en etterspent skjærvegg fra jordskjelvlaster
(Master thesis, 2013)Det ble tatt utgangspunkt i en oppspent veggskive med slakkarmering. Oppgaven gikk ut på å studere hvordan den oppspente armeringen og slakkarmeringen samvirker, når veggskiven utsettes for seismiske påkjenninger.Spennarmeringen ... -
A Response Spectrum Analysis of Wind Deflection in Railway Overhead Contact Lines Using Pseudo-Excitation Method
(Peer reviewed; Journal article, 2021)The wind deflection of overhead contact lines (OCLs) challenges the stable and safe operation of electrified railways. The steady wind causes the static deflection of the contact line, while the fluctuating wind leads to ... -
Revealing the role of hydroxyl groups in the adhesive properties of DOPA derivatives
(Master thesis, 2023)Blant alle naturlige klebematerialer er det kjent at polyfenoler er de vanlige kjemiske ingrediensene som spiller en betydelig rolle i klebeegenskapene. Mer spesifikt består den avgjørende kjemiske strukturen til naturlige ... -
Review of Sprayability of Wet Sprayed Concrete
(Peer reviewed; Journal article, 2020)Wet sprayed concrete quality is affected by more production factors than cast concrete, particularly due to the propulsion through the nozzle and the flash set caused by the set accelerator. Practitioners often use the ... -
