Parametric Study of a Tall Timber Building in Økern Centre
(Master thesis, 2021)I Økern Sentrum er det behov for byplanlegging. Dette inkluderer studie av et høyhus i tre plassert på Økerntunnelen. Tre er antatt å være en bedre løsning for dette formålet på grunn av lav egenvekt. Målet for oppgaven ... -
Dynamic properties of Stress-laminated Timber Bridges
(Master thesis, 2021)Denne masteren omhandler de dynamiske egenskapene til tverrspente limtreplatebroer. Fire forskjellige broer, ved fire forskjellige lokasjoner, ble målt. Enten ved et enkelt akselerometer eller flere akselerometer koblet i ... -

Tuned mass damper for self-excited vibration control: Optimization involving nonlinear aeroelastic effect
(Peer reviewed; Journal article, 2022)The conventional target for self-excited galloping/flutter control of a civil structure often focuses on the critical wind speed. In the present work, a nonlinear control target is introduced, i.e., to ensure that the ... -
Validation and Analysis on Numerical Response of Super-High-Speed Railway Pantograph-Catenary Interaction Based on Experimental Test
(Peer reviewed; Journal article, 2021)The numerical tools can be used to facilitate the design of the railway pantograph-catenary system. The validation of the current numerical results is mostly performed at a speed slower than 350 km/h. This paper aims at ... -
Assessment of the Current Collection Quality of Pantograph-Catenary with Contact Line Height Variability in Electric Railways
(Peer reviewed; Journal article, 2021)The numerical tools are widely used to facilitate the design of the railway catenary. Only radical results are obtained as the current assessment is generally performed without any practical errors. In this paper, the most ... -
Wind deflection analysis of railway catenary under crosswind based on nonlinear finite element model and wind tunnel test
(Peer reviewed; Journal article, 2022)This paper evaluates the railway catenary's wind deflection under crosswind based on wind tunnel experiments and a nonlinear finite element model. A catenary model is constructed based on the absolute nodal coordinate ... -
The Effects of Spatially Distributed Damping on the Contact Force in Railway Pantograph-Catenary Interactions
(Peer reviewed; Journal article, 2021)According to field measurements, the damping ratio of a railway catenary varies along the span length and shows an inherent uncertainty. In numerical simulations, it is common to assume a constant damping ratio. Herein, a ... -
Vibration Measurement and Wave Reflection Analysis in an Electrified Railway Catenary Based on Analytical Methods
(Peer reviewed; Journal article, 2021)The wave propagation property of the catenary directly affects the pantograph–catenary interaction performance. Specifically, wave reflection and transmission occurring at waveguide discontinuities, particularly at dropper ... -
Geometry deviation effects of railway catenaries on pantograph–catenary interaction: a case study in Norwegian Railway System
(Peer reviewed; Journal article, 2021)This paper presents a non-contact measurement of the realistic catenary geometry deviation in the Norwegian railway network through a laser rangefinder. The random geometry deviation is included in the catenary model to ... -
Laminar flow-induced vibration of a three-degree-of-freedom circular cylinder with an attached splitter plate
(Peer reviewed; Journal article, 2021)Splitter plates are widely used for drag reduction and vibration control or enhancement of circular cylinders. The effects of a splitter plate on the vertical flow-induced vibrations of a circular cylinder have been well ... -
Piezoelectric energy harvesting from vortex-induced vibration of a circular cylinder: Effect of Reynolds number
(Peer reviewed; Journal article, 2021)This study investigates the effects of the Reynolds number on the piezoelectric energy harvesting from vortex-induced vibrations (VIV) of a circular cylinder. The VIV-based piezoelectric energy harvester is simulated by a ...
