Recommendations of RILEM TC 287-CCS: thermo-chemo-mechanical modelling of massive concrete structures towards cracking risk assessment
(Peer reviewed; Journal article, 2021)These recommendations have been prepared by the corresponding working group within RILEM TC 287-CCS “Early-age and long-term crack width analysis in RC structures”, following work by the previously ceased RILEM TC 254-CMS ... -
Recommended practice for reporting experimental data produced from studies on corrosion of steel in cementitious systems
(Journal article; Peer reviewed, 2019)Experience has shown that many aspects of experimental design for studying steel corrosion in cementitious systems may significantly influence the obtained results. In the absence of standardized methods to study steel ... -
Reconfigurable Mechanical Anisotropy in Self-Assembled Magnetic Superstructures
(Peer reviewed; Journal article, 2021)Enhancement of mechanical properties in self-assembled superstructures of magnetic nanoparticles is a new emerging aspect of their remarkable collective behavior. However, how magnetic interactions modulate mechanical ... -
Reconstruction of surface pressures on flat plates impacted by blast waves using the Virtual Fields Method
(Peer reviewed; Journal article, 2023)An accurate description of surface pressure loads imposed by blast waves is crucial for the design of the next generation of blast-resistant structures. However, experimental techniques for non-intrusive, full-field surface ... -
Reduced order modelling for linear elastic problems with geometric variation
(Master thesis, 2019)Formålet med denne oppgaven er å undersøke bruken av reduserte modeller for å løse parametriske partielle differensialligninger. Dette vil bli gjort ved å konstruere og analysere reduserte modeller innen konstruksjonsmekanikk ... -
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 ... -
Repair Options for Corrosion-damaged Prestressed Concrete Structures
(Peer reviewed; Journal article, 2024)Prestressing of bridges allows construction of long spanned bridges made from thin structural members with high flexural and shear capacity. Studies have shown that some of the existing prestressed bridges are not meeting ... -
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 ... -
