Stempling av LB-bjelker i montasjetilstanden
(Master thesis, 2018)Denne oppgaven omhandler torsjonspåkjente LB-bjelker i montasjefasen. Det er lagt stor vekt på å undersøke om det kan oppstå uforutsette krefter og momenter i denne fasen som vanligvis ikke tas hensyn til ved dimensjoneringen ... -
Stiffened plates - Reduced Stress Method: Beregninger for platefelt - Alternativ metode
(Master thesis, 2013)Comparison of Effective width method and Reduced stress method is performed based on design procedures given in NS EN 1993-1-5The two methods lead to exactly equal critical buckling stress and strength for uniaxially loaded ... -
Stiffening surface lowers ice adhesion strength by stress concentration sites
(Peer reviewed; Journal article, 2023)Mechanically softening materials have been intensively investigated to reduce ice adhesion strength based on the adhesion failure mechanism. Achieving icephobic surfaces with both low ice adhesion strength and mechanical ... -
Stigmergi i Byggebransjen
(Master thesis, 2019)Denne masteroppgaven tar for seg stigmergi som en mekanisme for koordinering av arbeid. Den ser på stigmergi blant insekter, i menneskelig oppførsel, og i peer produksjon. Oppgaven utforsker også koordinering og organisering ... -
Stiverplater og konsollplater med trekantform, oppførsel og kapasitet
(Master thesis, 2014)I denne oppgaven er det utført seks forsøk med konsoll for å avdekke oppførsel og kapasitet til trekantede stiverplater. Fire av konsollene hadde trekantplate av S355 konstruksjonsstål og to hadde høyfaste plater i Weldox ... -
Stivhet til endeplateforbindelser i hulprofil
(Master thesis, 2013)Eurokode 3 del 1-8 (NS-EN 1993-1-8) gir beregningsregler for stivheten til knutepunkt med H- og I-profiler. Beregningen baserer seg på en komponentmetode der knutepunktet deles inn i basiskomponenter med kjent oppførsel. ... -
Stivhet til endeplateforbindelser i hulprofil
(Master thesis, 2012)I Eurokode 1993-1-8 er det gitt beregningsregler for å beregne stivhet til knutepunkter. Knutepunktene deles inn i basiskomponenter som kombineres for å beskrive den totale knutepunktsoppførselen. Reglene gitt i standarden ... -
Stochastic subspace identification of modal parameters during ice–structure interaction
(Journal article; Peer reviewed, 2019)Identifying the modal parameters of structures located in ice-infested waters may be challenging due to the interaction between the ice and structure. In this study, both simulated data from a state-of-the-art ice–structure ... -
Strain localization and ductile fracture in advanced high-strength steel sheets
(Journal article, 2017)An experimental-numerical approach is applied to determine the strain localization and ductile fracture of high-strength dual-phase and martensitic steel sheet materials. To this end, four different quasi-static material ... -
Strain-path change induced transients in flow stress, work hardening and r-values in aluminum
(Journal article, 2015)Commercially pure aluminum with random texture was prestrained either by rolling or by uniaxial compression, and then tested in uniaxial tension to study the transients in flow stress, work hardening and r-value induced ... -
Strain-rate and off-axis loading effects on the fibre compression strength of CFRP laminates: Experiments and constitutive modelling
(Peer reviewed; Journal article, 2020)A series of dynamic longitudinal compression tests have been performed on cross-ply IM7/8552 specimens cut at different off-axis angles to produce different combinations of compression and shear stresses. Together with ... -
Strength analysis of net structures
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:48, Doctoral thesis, 2009)The main goal of this PhD project was to develop a method for non-linear strength analysis of net structures applied in the aquaculture and fishing industries, e.g. net cages and trawls. The work focused on the aquaculture ... -
Strength analysis of prestressed reinforced bridge towers; Solution for a suspension bridge across Halsafjorden
(Master thesis, 2021)Halsafjorden er en av fjordene langs E39, der den nåværende fergen skal byttes ut med en mer effektiv krysningsløsning. Denne masteroppgaven undersøker alternativet som tar for seg en hengebru i ett spenn der begge tårnene ... -
Strength differential effect in age hardened aluminum alloys
(Journal article; Peer reviewed, 2017)The strength differential (SD) effect, as reported in literature over the past decades, is a discrepancy between the axial stresses in compression and tension. This study investigates the SD effect in aluminum alloys using ... -
Strength of Modern Masonry
(Master thesis, 2023)Grunnet den pågående revisjonen av Eurokode 6 og tilhørende nasjonale tillegg, har Standard Norge behov for nye tester på murverk, for å avgjøre hvorvidt verdiene for fasthet i det nåværende norske nasjonale tillegget ... -
Stress corrosion cracking of Ni2MnGa magnetic shape memory alloy in water and moist atmosphere
(Journal article; Peer reviewed, 2009)We prepared two kinds of cracks (surface cracks and transfixion cracks) to in situ study stress corrosion cracking of seven-layered (which is denoted as 7 M or 14 M) off-stoichiometric Ni2MnGa magnetic shape memory alloy ... -
Stress-laminated timber decks in bridges: Friction between lamellas, butt joints and pre-stressing system
(Peer reviewed; Journal article, 2020)Stress-laminated timber (SLT) decks in bridges are popular structural systems in bridge engineering. SLT decks are made from parallel timber beams placed side by side and pre-stressed together by means of steel rods. SLT ... -
