A Study of the Strength and the Physical Properties of Glacier-ice Runways - Assesment of Troll Airfield, Antarctica
Kallelid, Maren Salte (Master thesis, 2018)Airfields located in Antarctica are unique because the runways are constructed by glacier ice. Ice as a construction material differs from conventional runway materials in sense of strength, hardness and temperature ... -

Bakkan, Jonas; Gjerde, Anders; Sivarajah, Kireeshan (Bachelor thesis, 2021)Oppgaven tar utgangpunkt i å dimensjonere et slakkarmert betongdekke med understående betongføtter. Prosjektet som presenteres i oppgaven er et hotell som er lokalisert på Andørja i Ibestad kommune. I samarbeid med ... -
Automated Modal Parameters Identification During Ice-Structure Interactions
Wang, Chunlin; Nord, Torodd Skjerve; Li, Guoyuan (Chapter, 2022)Offshore structures are prone to damage caused by ice-induced vibrations. It is presently unknown to what extent different ice conditions change the properties of the structure, such as natural frequency, damping ratio, ... -

An expansion of Offshore wind will include the Baltic where sea ice is one of the major ... -
Data analysis and modelling for onboard support of marine operations
Wang, Chunlin (Doctoral theses at NTNU;2023:253, Doctoral thesis, 2023)The ever-increasing exploration of ocean resources has led to more frequent and intensive marine operations. However, marine operations are vulnerable to accidents due to unpredictable environmental factors and human ... -
Demonterbare knutepunkt i hulldekkeskive
Falck, Fredrik With; Nilsen, Helle Bergitte; Gundesø, Odin Høyland (Bachelor thesis, 2022)Forutsetningen for prosjektering av bygg i dag er at de skal rives ved endt levetid, som gir lite rom for gjenbruk. I kombinasjon med dagens klimafokus er målet nå mer rettet mot bygg som ved endt levetid kan skape gode ... -
Dimensjonere og sammenligne etterspent dekke mot planlagt hulldekke i Sundebygget
Ekroll, André; Sætre, Stig Ove Lekven; Sandal, Erik Lilleås (Bachelor thesis, 2021)I denne oppgaven dimensjoneres et utvalg av etasjeskillere i det nye studenthuset (Sundebygget) ved NTNU Ålesund som etterspente dekker. Hensikten med oppgaven er å finne ut om opprinnelig løsning med hulldekke er det beste ... -
Dimensjonering av peler i permafrost
Ramsvik, Caroline; Bozkurt, Ida Chatrine Rangul (Bachelor thesis, 2021)Vår bacheloroppgave handler om å undersøke ulike typer fundamentering i arktiske forhold. På Svalbard finnes det permafrost helt ned til 450 m enkelte plasser. På grunn av dette kan man ikke fundamentere på samme måte som ... -
Estimation of the full-field dynamic response of a floating bridge using Kalman-type filtering algorithms
Petersen, Øyvind Wiig; Øiseth, Ole; Nord, Torodd Skjerve; Lourens, Eliz-Mari (Journal article; Peer reviewed, 2018)Numerical predictions of the dynamic response of complex structures are often uncertain due to uncertainties inherited from the assumed load effects. Inverse methods can estimate the true dynamic response of a structure ... -
Experimental and numerical studies related to failure of first-year ice ridges against fixed vertically sided structures
Ervik, Åse (Doctoral theses at NTNU;2019:192, Doctoral thesis, 2019) -
Force and response estimation on bottom-founded structures prone to ice-induced vibrations
Nord, Torodd Skjerve (Doctoral thesis at NTNU;2015:217, Doctoral thesis, 2015)Various types of bottom-founded structures, including lighthouses, quay structures, mono-pod platforms, multi-legged platforms, caisson-retained islands and bridges, are located in ice-infested waters. Level ice can ... -
Ice-induced vibrations of the Norströmsgrund lighthouse
Nord, Torodd Skjerve; Samardzija, Ilija; Hendrikse, Hayo; Bjerkås, Morten; Høyland, Knut Vilhelm; Li, Hongtao (Journal article; Peer reviewed, 2018)The signature and occurrence of frequency lock-in (FLI) vibrations of full-scale offshore structures are not well understood. Although several structures have experienced FLI, limited amounts of time histories of the ... -
Inverse identification of buffeting and self-excited wind loads on the {Hardanger} bridge from acceleration data
Petersen, Øyvind Wiig; Øiseth, Ole Andre; Nord, Torodd Skjerve; Lourens, Eliz-Mari (Chapter, 2019)The traditional wind load assessment for long-span bridges rely on assumed models for the wind field and aerodynamic coefficients from wind tunnel tests, which usually introduces some uncertainties. It is therefore desired ... -
Miljøgevinst ved bruk av basaltfiber i landbasert oppdrettsmerd
Lu, Jan-Erik Haraldsen; Karlsen, Jul Kristian Notø (Bachelor thesis, 2022)Fiberarmering forbedrer betongen ved å gjøre den mer duktil og motvirker riss med bedret strekkfasthet.
