Fibre reinforced concrete structures: shear capacity of beams and slabs
(Master thesis, 2011)This report contains studies of shear force and punching shear capacity of steel-fibre reinforced concrete. Beam tests for shear and small beam tests for residual tensile strength reported in my project assignment [9] are ... -
Fibre Reinforced Concrete: Evaluation of test methods and material development
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:297, Doctoral thesis, 2011)Concrete is a structural material with excellent properties when subjected to compression, butthe abilities to resist tensile stresses are rather poor. The concrete’s tensile zone is normallyreinforced with large continuous ... -
Fibre Reinforced Concrete: Optimization of fibre content and shear capacity of dapped-end beams
(Master thesis, 2013)Fibre reinforced concrete is a type of concrete which improves the fracture characteristics and structural behaviour through the fibres ability to bridge cracks: it offers a much more ductile response. Thus, the principal ... -
Fibre Reinforcement in Load Carrying Concrete Structures: Laboratory and Field Investigations compared with Theory and Finite Element Analysis
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:50, Doctoral thesis, 2008)Fibre reinforcement can provide an alternative to conventional steel bars in order to improve the efficiency and working conditions on construction sites and in the prefabrication industry. Through the fibres ability to ... -
Fibre-reinforced Self-compacting Concrete: Prediction of Rheological Properties
(Master thesis, 2012)The purpose of this thesis is to investigate the relationship between measured rheology and proportioning properties with particular attention to maximum packing fraction, thickness of fiber lubricating matrix and fiber ... -
Fibre-reinforced thermoplastics
(Master thesis, 2011)This thesis presents experimental tests of fibre-reinforced polypropylene, as well as calibration of material coefficients and simulations of experimental tests. The focus is on exploring the dependence on loading direction ... -
Fibre-reinforced thermoplastics
(Master thesis, 2011)SIMLab aims to develop a constitutive material model for fibre-reinforced thermo plastics. To do this an experimental database is needed. The main goal for this thesis is to provide this database by performing experimental ... -
Field investigations of crosswinds and vehicle-driver response on bridges
(Doctoral theses at NTNU;2023:41, Doctoral thesis, 2023)There are currently no scientific, evidence-based guidelines for designing windrelated traffic regulations on Norwegian road bridges. The topic of crosswindexposed vehicles on bridges has been studied theoretically, ... -
Field Measurements in Mechanical Testing Using Close-Range Photogrammetry and Digital Image Analysis
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:95, Doctoral thesis, 2012)This thesis contains a study on using numerical post-processing of recorded digital images from mechanical experiments to obtain continuous measurements of both displacement and strain fields of a particular specimen ... -
Field Station Sandnessjøen, Effect of cracks in concrete after 25 years - Data report
(Research report, 2020)Tre opprissede betongbjelker støpt med forskjellige bindemiddelsammensetninger ble undersøkt etter 25 års marin eksponering ved feltstasjon Sandnessjøen. Betongbjelkene ble undersøkt med tanke på effekten av riss på ... -
A field study on thermal comfort and cooling load demand optimization in a tropical climate
(Peer reviewed; Journal article, 2021)Energy consumption to cool an indoor environment is a substantial part of total energy end-use, particularly in a tropical climate with high energy demand for cooling. To improve energy efficiency, cooling systems can be ... -
Filler and Water Reducer Effects on Sedimentation, Bleeding and Zeta-Potential of Cement Paste
(Journal article; Peer reviewed, 2018)Bleeding and sedimentation quantify the stability of fresh cement paste, whereas the addition of fillers and water reducers affect the stability. The effect of various types of fillers and water reducers was investigated ... -
Finite Element Analyses of Spudcan Penetration Using CEL Method
(Master thesis, 2013)A hazard during installation of jack-up spudcans is punch-through, which is characterized by a peak resistance, followed by a significant reduction in spudcan resistance. This might lead to an uncontrolled rapid leg ... -
Finite element analysis of mitral valve annuloplasty in Barlow's disease
(Peer reviewed; Journal article, 2022)Barlow’s Disease affects the entire mitral valve apparatus causing mitral regurgitation. Standard annuloplasty procedures lead to an average of 55% annular area reduction of the end diastolic pre-operative annular area in ... -
Finite element analysis of porous polymer coated pipelines subjected to impact
(Peer reviewed; Journal article, 2021)Subsea steel pipelines are often coated with external polymer coatings. While primarily applied for corrosion protection and thermal insulation, such coatings have been shown to contribute significantly to the energy ... -
Finite element analysis used to optimize design and calculate fatigue of peripheral-lines on Aker Drilling Risers clip connector
(Master thesis, 2011)Increasing prices- and high demand for hydrocarbons worldwide have encouraged oil companies to explore in deeper, more vulnerable- and hasher ocean environments. A consequence of working in such areas is that the requirements ... -
