The effect of reinforcement corrosion on the structural behaviour of prestressed bridges in the Norwegian coastal regions
(Chapter, 2017)Prestressed concrete (PC) is one of the main structural materials used in Norway for bridge structures. Prestressed and precast concrete beams were even used for building the historical Atlantic Road, which has the status ... -
The effect of the steel-concrete interface on chlorideinduced corrosion initiation in concrete: a critical review by RILEM TC 262-SCI
(Journal article; Peer reviewed, 2019)The steel–concrete interface (SCI) is known to influence corrosion of steel in concrete. However, due to the numerous factors affecting the SCI—including steel properties, concrete properties, execution, and exposure ... -
The Effects of Near-fault Earthquakes On a High-rise Structure In The Oslo Area
(Master thesis, 2012)The objective of the presented research is to evaluate the seismic response of a high-rise structure located in a seismic environment. For this purpose, the Oslo Plaza building located in Oslo, Norway, was chosen. A numerical ... -
The Effects of Numerical Modeling Assumptions in Seismic Design
(Master thesis, 2018)Complex numerical models have been developed during the last decades. They are able to model complex phenomena that may occur in a structure when subjected to seismic excitations, including nonlinear material response and ... -
The Function of Form: Conceptual Design of Modern Shell Structures
(Master thesis, 2013)Concrete shells were a hit at the middle of the nineteenth century, but have since decreased in popularity. Landmark buildings of recent years may indicate that curved shells are again in vogue among architects. Shell ... -
The Hardanger Bridge monitoring project: Long-term monitoring results and implications on bridge design
(Journal article; Peer reviewed, 2017)In design of slender suspension bridges, which are prone to wind excitation, accurate prediction of dynamic response is essential for reliable designs. However, dynamic response calculations involve many sources of ... -
The influence of fiber dispersion on the mechanical response of aortic tissues in health and disease: a computational study
(Journal article; Peer reviewed, 2018)Changes in the structural components of aortic tissues have been shown to play a significant role in the pathogenesis of aortic degeneration. Therefore, reliable stress analyses require a suitable and meaningful constitutive ... -
The Influence of Grading on the Reliability of Timber Structures
(Master thesis, 2015)In the present thesis, the influence of grading on the reliability of timber structures is analyzed. The thesis develops necessary expressions and explains methods for performing this type of analysis, and presents an ... -
The interaction between calcium lignosulfonate and cement
(Doctoral theses at NTNU;2017:20, Doctoral thesis, 2017)Modern concrete applications intensify the need for highly-flowable concretes, which are at the same time durable and possess good mechanical properties. The addition of plasticizers to the concrete mix allows obtaining ... -
The Need for Standards in Low Ice Adhesion Surface Research: A Critical Review
(Journal article; Peer reviewed, 2019)Low ice adhesion surfaces are a promising anti-icing strategy. However, experimentally obtained ice adhesion strengths are so far not transferable or comparable, and they are very sensitive to the experimental set-up and ... -
The Parametric design of adaptive joints
(Master thesis, 2017)Building information modeling (BIM) has had a big impact on modern engineering. Through the information contained in the models, engineers are able to interpret and organize a vast amount of data. During a conceptual design ... -
The Particle-Matrix model: limitations and further improvements needed
(Journal article; Peer reviewed, 2017)According to the Particle-Matrix Model (PMM) philosophy, the workability of concrete depends on the properties of two phases and the volumetric ratio between them: the fluid matrix phase (≤ 0.125 mm) and the solid particle ... -
The possibility of using reinforcement bars of aluminium in concrete structures
(Master thesis, 2018)In this study, the possibility of using aluminium as reinforcement in concrete structures is investigated, with use of a low pH concrete. The thesis is assigned by NTNU, and is a part of the science project DARE2C, a project ... -
The role of concrete resistivity in chloride-induced macro-cell corrosion of reinforcement
(Doctoral thesis at NTNU;2015:324, Doctoral thesis, 2015)Norwegian concrete structures are exposed to salt contamination from both sea water and de-icing salts. Chlorides penetrate the concrete cover and initiate corrosion of the reinforcement. The deterioration process can ... -
The role of quench rate on the plastic flow and fracture of three aluminium alloys with different grain structure and texture
(Journal article; Peer reviewed, 2020)The yielding, plastic flow and fracture of age hardenable aluminium alloys depend on the quench rate to room temperature after the solution heat-treatment at elevated temperature and before the artificial ageing. We ... -
The Rollout Stress Ribbon Bridge
