On strain-rate dependent properties of model ice for simulating ice-induced vibrations
(Master thesis, 2021)The subject of ice-induced vibrations on bottom-founded vertically sided offshore structures has gained renewed interest with the growth of the offshore wind industry, stimulated by many nations committing to ambitious ... -
On the concept of sustainability – assessing the sustainability of large public infrastructure investment projects
(Journal article; Peer reviewed, 2014)Assessing the sustainability of large public investment projects within the general framework of three-pillar thinking is a complex affair. Such ventures involve multiple actors – e.g. planners from various disciplines ... -
On the convexity of yield and potential surfaces in rotational hardening critical state models
(Chapter, 2018)This article shows that a common formulation often used for an anisotropic modified cam clay yield and potential surface with a modified Lode angle dependency may become concave for high values of anisotropy. Concave ... -
On the difference between project management success and project success
(Chapter, 2013)In construction projects, the perspective of the supply side (as represented by the design team) should converge with the business logics directing the demand side. Project management success is measured against the ... -
On the durability and lifetime prediction of filament wound composites
(Doctoral theses at NTNU;2024:222, Doctoral thesis, 2024)This thesis investigates the durability and aging behavior of glass fiber/vinylester filament wound composites (FWCs) coupons obtained from real-life structures under various environmental conditions. Divided into four ... -
On the Earth Pressure Coefficient at Rest During Creep
(Master thesis, 2015)Many geotechnical problems requires assumptions regarding the initial stress state in the soil to be made. The earth pressure coefficient at rest, K0, describes the relationship between horizontal and vertical effective ... -
On the Feasibility of Real-time Sea Level Monitoring using Ground-based GNSS-Reflectometry Measurements
(Master thesis, 2020)GNSS Reflektometri (GNSS-R) er en fjernmålingsteknikk som har fått mye oppmerksomhet i nyere tid. I denne avhandlingen blir teorien bak GNSS reflektometri presentert, og et eksperiment er gjennomført for å vurdere mulighetene ... -
On the ice and wind conditions in the northern part of the Gulf of Bothnia leading ice-induced vibrations
(Chapter, 2020)In ice infested regions drift ice can give serious damage to offshore structures and ships. The origin of the drifting ice is the winds and the currents. However, it is known that the Gulf of Bothnia does not have strong ... -
On the influence of input data uncertainty on sewer deterioration models – a case study in Norway
(Peer reviewed; Journal article, 2021)Visual inspection is currently the industry standard for assessing sewer and stormwater pipelines – a method prone to uncertainties as shown by previous studies. The data gathered from the visual inspection procedures is ... -
On the isotache viscous modelling of clay behaviour using the hyperplasticity approach
(Journal article; Peer reviewed, 2022)The thermodynamically based hyperplasticity framework is employed to develop a hyper-viscoplastic constitutive model describing clay's creep and rate-dependent behaviour. The proposed model complies with the concept of the ... -
On the Mechanical Properties of Cement Grout
(Master thesis, 2012)During pressure grouting of ground anchors in non-cohesive soils the water in the grout is filtrated out, producing a stiff filter cake material. Often the grouting is done in more than one stage so that the filter cake ... -
On the Modelling of State-Dilatancy and Mechanical Behaviour of Frictional Materials
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:72, Doctoral thesis, 2014)Understanding and characterizing the mechanical behaviour of soils is an important area of engineering for geotechnical engineers. This is for a good reason. Soils, as engineering materials, carry structures of different ... -
On the Remote Sensing of the Atmosphere and Ocean Using Direct and Reflected GNSS Signals
(Doctoral thesis, 2022)The Global Navigation Satellite Systems (GNSS) signals have shown great potential for remote sensing applications. The ubiquitous GNSS signals in direct or reflected geometry can be processed to retrieve different geophysical ... -
On the Response of Polarimetric GNSS-Reflectometry to Sea Surface Roughness
(Journal article; Peer reviewed, 2021)Reflectometry of Global Navigation Satellite Systems (GNSS) signals from the ocean surface has provided a new source of observations to study the ocean-atmosphere interaction. We investigate the sensitivity and performance ... -
On the Transferability and Comparability of Sewer Deterioration Models - A Case Study on Norwegian Sewer Data
(Master thesis, 2023)Avløpssystemer er kritisk infrastruktur for kommuner, og ettersom tilstand til avløpsrørene forverres over tid, er kunnskap om deres n˚aværende og fremtidige tilstand ett viktig ledd for bedre planlegging av rehabilitering ... -
On the use of multi-objective optimization for multi-site calibration of extensive green roofs
(Journal article; Peer reviewed, 2022)Conceptual hydrological models are practical tools for estimating the performance of green roofs. Such models require calibration to obtain parameter values, which limits their use when measured data are not available. One ... -
On the use of sawdust and wood chips in geotechnical engineering - Laboratory characterization
(Master thesis, 2021)I 1963 og 1964 ble to forsøksfelt opprettet av Norges Geotekniske Institutt (NGI) og Statens vegvesen med den hensikt å undersøke setninger på torv. Sirkulære fyllinger av sand inkluderende sagmugglag med tykkelse på 1.0–2.0 ... -
One Dimensional consolidation in IL and CRS oedometer: A study of strain rates and time dependency
