Sensitivity in the dynamic response estimation of pantograph-catenary interaction, due to time step and cut-off frequency - A numerical study
(Master thesis, 2017)This thesis investigates the sensitivity in the dynamic response when simulating the pantograph-catenary interaction due to time step and cut-off frequency. In addition, the contact formulation stated in standard EN50318 ... -
Sensitivity-based finite element model updating of a pontoon bridge
(Journal article, 2017)Numerical models of large civil engineering structures are prone to errors and uncertain system parameters, which inevitably affect the ability of such models to accurately predict dynamic behavior. Finite element (FE) ... -
Settlements at several masts of the power line constructed on sedimentary permafrost deposits in Sisimiut, West-Greenland: Field- and lab work, data processing and thermal modelling
(Master thesis, 2023)The electricity of Greenland’s second largest town, Sisimiut (West -Greenland), is supplied by a hydropower plant, located some 20 km north from the town. In late 2021, Nukissiorfiit – the Greenland public utilities company ... -
Shape and Size of Particles Scaled from Concrete Surfaces during Salt Frost Testing and Rapid Freeze/thaw in Water
(Peer reviewed; Journal article, 2021)Thickness (T), Length (L), Width (W) and size distribution of scaled concrete particles in frost testing were measured. T (mm) increases with particle size surprisingly similarly for different concrete qualities and frost ... -
Shape optimization of an aluminium girder for a long-span suspension bridge: Aerodynamic stability, buffeting response and suppression of vortex induced vibrations
(Master thesis, 2021)Det er planlagt å bygge en hengebro over Langenuen som en del av målsetningen om å bygge ferjefri E39 langs kysten av Vest-Norge. Det planlagte konseptet av broen inkluderer et hovedspenn på 1220 m, som vil gjøre den til ... -

Shear assessment of a reinforced concrete bridge deck slab according to level-of-approximation approach
(Journal article; Peer reviewed, 2018)Reinforced concrete (RC) slabs without shear reinforcement are commonly used for existing bridge structures. For such structures, shear and punching can be the governing failure modes at the ultimate limit state if subjected ... -
Shear Capacity Assessment of an Existing Prestressed Concrete Bridge with Corrosion Damage
(Master thesis, 2017)The thesis contains shear capacity calculations of the structural beams in The Hulvågen Bridge, a concrete element bridge consisting of prefabricated and pre-tensioned beams with a continuous cast-in-place bridge deck. The ... -
Shear Capacity of Axially Loaded Concrete Beams without Transverse Reinforcement
(Master thesis, 2020)Betongbjelker blir ofte brukt som lastbærende elementer i blant annet bygninger, broer og i offshorekonstruksjoner, hvor de utsettes for forskjellige lastvirkninger. Kapasiteten til bjelkene avhenger både av størrelsen på ... -

Shear lag effects on global bending moments in a long-span pontoon bridge under self-weight, traffic and environmental loads
(Peer reviewed; Journal article, 2023)The present paper deals with a systematic study of the shear lag effect on the bending moment distribution in girders of representative pontoon-type floating bridges (PTFBs). Comparative and parametric studies for ... -
Shear Properties of Nordic Glulam CE L40c
(Master thesis, 2012)The aims of this report are to investigate whether a new specimen is suitable for shear testing and to investigate the shear properties of Nordic glulam CE L40c. A total number of 56 shear tests were carried out. The ... -
Shock tube test with coupled 1D-3D models in EUROPLEXUS
(EUR;, Research report, 2016)This report illustrates the use of coupled 1D-3D models for the simulation of shock tube experiments by the EUROPLEXUS code. This, combined with new features allowing appropriate piloting of the time increment in the ... -
Shock Tube Testing and Modelling of Annealed Float Glass
(Journal article; Peer reviewed, 2018)Failure of glass is dominantly brittle, and is caused by microscopic flaws randomly distributed on the surface. Fracture mainly initiates in these flaws, and this leads to a high variability in the glass strength, which ... -
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 ... -
A simple method enabling efficient quantitative analysis of the Portevin–Le Chatelier band characteristics
(Peer reviewed; Journal article, 2022)Localized deformation bands are often observed in materials exhibiting the Portevin–Le Chatelier (PLC) effect. However, efficient quantitative analysis of PLC bands remains challenging. A novel method is thus proposed in ... -
