(Master thesis, 2022)Abstract will be available on 2025-06-11 -
Behavior of Post-Tensioned concrete box girder with multiple damaged tendons A Case Study of the Sykkylvsbrua
(Master thesis, 2022)Hovedformålet med denne masteroppgaven var å undersøke skadene i enkelt støttede boksbjelkerbroer. Dette ble utført ved å utføre ikke-lineær analyse i Finite elementanalyseprogrammet DIANA FEA 10.5 Oppgaven er delt inn i ... -
One the use of Machine Learning in the design of structures.
(Master thesis, 2022)FE-analyse kan tilnærmes på en maskin-lærings måte. Man kan tolke simuleringene som input til nevrale netverks modeller og forsøke å predikere en eller flere output. Denne masteroppgaven utforsker hvor godt modellene ... -
A siamese network-based non-contact measurement method for railway catenary uplift trained in a free vibration test
(Peer reviewed; Journal article, 2020)The vibration of the catenary that is initiated by the passing pantograph has a direct influence on the pantograph–catenary contact performance. Monitoring the dynamic uplift of the catenary can help inspectors to evaluate ... -
Constitutive modeling of a graded porous polymer based on X-ray computed tomography
(Peer reviewed; Journal article, 2020)This work focuses on the constitutive modeling of a graded porous polymer pipeline coating based on X-ray micro computed tomography (XRMCT). Previous work has revealed that finite element (FE) models generated from XRMCT ... -
Use of Concrete for Road Infrastructure: A SWOT Analysis Related to the three Catchwords Sustainability, Industrialisation and Digitalisation.
(Peer reviewed; Journal article, 2019)This paper aims at identifying the direction for more sustainable development of the use of concrete in road infrastructure in an industrialised context. The increase in the global mean temperature is one of the most severe ... -
The effect of infill walls on the seismic behavior of boundary columns in RC frames
(Peer reviewed; Journal article, 2016)scaled, three-story three-bay RC frame with masonry infill walls was studied experimentally and numerically. Pseudo-dynamic test results showed that despite following the column design provisions of modern seismic codes ... -
Steel beams with unstiffened web openings
(Master thesis, 2022)Den europeiske standardiseringskomiteen, CEN, har jobbet med en utvidelse av Eurokode 3: Design av stålkonstruksjoner – Del 1-1: Generelle regler og regler for bygninger, som skal hete «EN 1993-1-13: Bjelker med åpninger ... -
Onion inspired hydrate-phobic surfaces
(Peer reviewed; Journal article, 2022)Hydrate plugging in gas- and oil-production and transport systems has long been a critical challenge. Traditional hydrate mitigation strategies through applying chemicals and thermal destabilization are costly and ... -
Ballistic impact of structural steels at low temperatures
(Peer reviewed; Journal article, 2022)Steels are usually stronger at low temperatures than at high temperatures. But low temperatures are, particularly in combination with high strain rates and high stress triaxiality ratios, known to cause embrittlement. The ... -
Characteristics of cyclic undrained model SANISAND-MSu and their effects on response of monopiles for offshore wind structures

A predictive model unifying hydrogen enhanced plasticity and decohesion
(Peer reviewed; Journal article, 2022)The detrimental effect of hydrogen on metals which manifests itself as a transition from a ductile to a brittle failure mode is, for the first time, incorporated into a unified continuum-scale predictive framework. The ... -
Portland Clinker-Fly Ash Cements – Relation between Compressive Strength and Microstructure
(Chapter, 2021)Portland cements were made by mixing 4 different clinkers with 2 gypsum levels and 0-5% limestone powder. The compressive strength after 28 days of curing varied from 40 (5802) to 70 MPa (9718 psi) for mortar with equal ... -
Chloride binding in concrete: recent investigations and recognised knowledge gaps: RILEM Robert L’Hermite Medal Paper 2021
(Journal article; Peer reviewed, 2021)A theoretical understanding of chloride binding is urgently needed if we are to use the new low-CO2 composite cements in reinforced concrete structures exposed to chloride-loaded environments. The empirical models and ... -
Optimization framework for cost and carbon emission of timber floor elements
(Peer reviewed; Journal article, 2021)Long-span timber floor elements increase the adaptability of a building and they exhibit a significant market potential. High cost of the floor elements is a challenge, and the timber sector is under substantial pressure ... -
Experimental carbonation study for a durability assessment of novel cementitious materials
(Peer reviewed; Journal article, 2021)Durability predictions of concrete structures are derived from experience-based requirements and descriptive exposure classes. To support durability predictions, a numerical model related to the carbonation resistance of ... -
A novel three-dimensional boron phosphide network for thermal management of epoxy composites
(Peer reviewed; Journal article, 2022)Recently, construction of effective three-dimensional (3D) heat transfer networks inside polymer has emerged as a promising design strategy to improve the isotropic thermal conductivity for electronic packaging materials. ... -
Modelling of Stainless Steel AISI 316L in Finite Element Simulations
(Peer reviewed; Journal article, 2021)This paper addresses numerical modelling of a rolled, austenitic stainless steel of grade AISI 316L, corresponding to EN 1.4404. The study comprises uniaxial tension tests at a range of temperatures (from –20°C to 200°C) ... -
