Extreme responses and associated uncertainties for a long end-anchored floating bridge
(Peer reviewed; Journal article, 2020)Very-long floating bridges represent an innovative marine structure for crossing wide and deep fjords. During the design of a floating bridge, extreme structural responses at a specified probability of exceedance are ... -
Flutter derivatives from free decay tests of a rectangular B/D?=?10 section estimated by optimized system identification methods
(Journal article; Peer reviewed, 2018) -
Impact assessment of a wind turbine blade root during an offshore mating process
(Journal article; Peer reviewed, 2019)Single-blade installation is a popular method for installing blades on bottom-fixed offshore wind turbines. A jack-up crane vessel is often employed, and individual blades with their roots equipped with mechanical joints ... -
Increasing ductility in heavily reinforced LWAC structures
(Journal article; Peer reviewed, 2014)This study focuses on the ductility of lightweight aggregate concrete (LWAC) in compression. For practical purposes, the well-known brittleness of LWAC compared to normal density concrete has limited the use of the material. ... -
Influence of hot-dip galvanization on the fatigue performance of high-strength bolted connections
(Peer reviewed; Journal article, 2024)In the present work, the influence of hot-dip galvanization (HDG) on the fatigue behaviour of high-strength bolted details is investigated through a set of 15 constant-amplitude tests. Cyclic behaviour of coated specimens ... -
Influence of large-scale asperities on the shear strength of concrete-rock interface of small buttress dams
(Peer reviewed; Journal article, 2021)This paper presents an investigation of the influence of large-scale asperities on the shear strength of four physical models of a pillar (also known as buttress web)from Kalhovd dam in Norway. The objective was to observe ... -
Investigations of the long-term extreme buffeting response of long-span bridges using importance sampling Monte Carlo simulations
(Peer reviewed; Journal article, 2022)Several studies have shown that site measurements of the buffeting responses of long-span bridges do not always agree with predictions from analytical models. The observed discrepancy is believed to be explained by the ... -
Load effects in reinforced concrete beam bridges affected by alkali–silica reaction—Constitutive modelling including expansion, cracking, creep and crushing
(Peer reviewed; Journal article, 2021)Material modelling, from the micro to the macro level, of concrete affected by alkali–silica reaction (ASR) has been devoted a lot of research. However, the application of the material models in structural analyses of ... -
Long-term extreme buffeting response of cable-supported bridges with uncertain turbulence parameters
(Peer reviewed; Journal article, 2021)Although the full long-term method (FLM) is recognized as the appropriate way to identify the design stresses of marine structures subjected to stochastic environmental loading, the FLM has not yet been adopted for the ... -
Long-term monitoring of wind field characteristics and dynamic response of a long-span suspension bridge in complex terrain
(Journal article; Peer reviewed, 2017)Long-term monitoring data of wind velocities and accelerations on the Hardanger Bridge are used to investigate the relationship between the wind-loading and response processes. The extensive measurement system consisting ... -
Modified cracked membrane model for consistent crack width predictions of reinforced concrete structures subjected to in-plane loading
(Journal article; Peer reviewed, 2019)The modified cracked membrane model (MCMM) presented in this paper was formulated to facilitate a mechanical calculation model that predicts crack widths in reinforced concrete (RC) structures subjected to in-plane loading ... -
Moment resisting on-site splice of large glulam elements by use of mechanically coupled long threaded rods
(Journal article; Peer reviewed, 2018)Large spans of modern timber bridges can be achieved by use of glulam arches with network hanger configuration. Since transportation and production limit the length of timber elements, the glulam arches must be spliced on ... -
Moving point load approximation from bridge response signals and its application to bridge Weigh-in-Motion
(Peer reviewed; Journal article, 2021)This paper presents a revised theoretical interpretation for the analysis of bridge response signals arising during a vehicle passage. The derivation shows that it is possible to approximate the forcing function from bridge ... -
A multi-surface interface model for sequentially linear methods to analyse masonry structures
(Peer reviewed; Journal article, 2021)In the finite element modelling of masonry structures, the micro-modelling technique of differentiating the continuum into a linear elastic bulk, and interfaces representing non-linear joints is common. However, this ... -
A novel joint for driven concrete geothermal energy pile foundations
(Peer reviewed; Journal article, 2024)Geothermal energy pile foundations are among the most common types of energy geostructures which provide both structural support and can be used as a source with ground source heat pumps for heating and cooling buildings. ... -
Numerical and analytical studies of ship deckhouse impact with steel and RC bridge girders
(Peer reviewed; Journal article, 2021)Bridges crossing navigable waterways are under the threat of accidental collisions from passing ships. However, previous research focus was mainly placed on ship collision with bridge substructures while ship-bridge ... -
