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 ... -
Operational modal analysis of an end-supported pontoon bridge
(Journal article; Peer reviewed, 2017)A comprehensive monitoring system is installed and currently in operation on the Bergsøysund Bridge, an end-supported floating pontoon bridge, collecting data on accelerations, displacements, waves, and wind. Using ... -
Optimization framework for cost and carbon emission of timber floor elements
(Peer reviewed; Journal article, 2021)Long-span timber floor elements increase the adaptability of a building and they exhibit a significant market potential. High cost of the floor elements is a challenge, and the timber sector is under substantial pressure ... -
Prediction of long-term extreme load effects due to wave and wind actions for cable-supported bridges with floating pylons
(Journal article; Peer reviewed, 2018)The characteristic values of the extreme environmental load effects should correspond to a specified annual probability of exceedance. These load effects can be calculated using short-term or long-term methods. The full ... -
Prediction of long-term extreme load effects due to wind for cable-supported bridges using time-domain simulations
(Journal article, 2017)Many long-span bridges that are slender and susceptible to wind-induced vibrations are currently under construction all over the world. As nonlinear structural behavior and nonlinear displacement-dependent wind loads become ... -
Railway bridge damage detection using vehicle-based inertial measurements and apparent profile
(Journal article; Peer reviewed, 2017)The presence of damage in a railway bridge alters its stiffness and consequently, its static and dynamic response to loading. The dynamic response of a railway bridge to loading produces a dynamic response in the passing ... -
Rate dependent fracture of monolithic and laminated glass: Experiments and simulations
(Peer reviewed; Journal article, 2020)Glass is a brittle material known to possess large scatter in its fracture strength, which is caused by the existence of microscopic surface flaws. Fracture in glass generally originates from stress concentrations around ... -
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) ... -
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 ... -
A theoretical study of the dynamic response of planar timber frames with semi-rigid moment-resisting connections subjected to wind loads
(Peer reviewed; Journal article, 2021)The dynamic response of semi-rigid timber frames subjected to wind loads is investigated numerically in this paper. The dynamic response of more than one million unique frames with different parameters was assessed with ... -
Toward identifying the ASR-induced stresses from displacement measurements and crack observations—Demonstration on a beam bridge in Norway
(Peer reviewed; Journal article, 2022)Alkali–silica reaction (ASR) in concrete causes expansion and degradation of the material, which might give adverse structural consequences. From the structural engineer point view, the greatest concern is if ASR leads to ... -
Towards a better understanding of the ultimate behaviour of LWAC in compression and bending
(Journal article; Peer reviewed, 2017)There is a general scepticism regarding the use of lightweight aggregate concrete (LWAC) for structural applications. This concern is attached to the more brittle post-peak material behaviour and smoother crack surfaces ...
