A numerical study of beam-to-column joints subjected to impact
(Journal article; Peer reviewed, 2016)Limited documentation is concerned with the behaviour of steel joints subjected to severe impulsive loading originating from incidents such as explosions or impact. In this paper, finite element simulations are used to ... -
Application of European design principles to cross laminated timber
(Journal article; Peer reviewed, 2018)The design of cross laminated timber (CLT) structures is not included in the current version of European structural timber design standards of EN 1995 (Eurocode 5, EC 5). Due to the increasing importance of CLT, in different ... -
Assessment of the failure behaviour and reliability of timber connections with multiple dowel-type fasteners
(Journal article; Peer reviewed, 2018)Connections with metal dowel-type fasteners are important details in timber construction, connecting single members and elements to larger structures. The load-carrying capacity can be described by different failure modes ... -
Buffeting response of long-span bridges considering uncertain turbulence parameters using the environmental contour method
(Peer reviewed; Journal article, 2020)Full-scale monitoring of the Hardanger Bridge has revealed significant turbulence-induced variability in the measured acceleration response. In this paper, a probabilistic model is used to describe the uncertain turbulence ... -
Deep autoencoder architecture for bridge damage assessment using responses from several vehicles
(Peer reviewed; Journal article, 2021)Vehicle-assisted monitoring is a promising alternative for rapid and low-cost bridge health monitoring compared to direct instrumentation of bridges. In recent years, centralized management systems for fleets of heavy ... -
Development of an index for quantification of structural dynamic response in a railway catenary section
(Peer reviewed; Journal article, 2020)In an attempt to quantify the amount of the dynamic reaction in a railway catenary system due to the dynamic action created by the interaction with the pantograph of the train, a catenary dynamic index (CDI) is developed. ... -
Drive-by scour monitoring of railway bridges using a wavelet-based approach
(Journal article; Peer reviewed, 2019)This paper numerically investigates the feasibility of using bogie acceleration measurements from a passing train to detect the presence of bridge scour. The Continuous Wavelet Transform is used to process the simulated ... -
Dynamics of long multi-trailer heavy vehicles crossing short to medium span length bridges
(Peer reviewed; Journal article, 2021)Around the world, many countries experience an increase in the demand for freight to be transported by road. One solution is to introduce larger heavy vehicles, which have the capability of transporting more freight. These ... -
Evolution of bridge frequencies and modes of vibration during truck passage
(Journal article; Peer reviewed, 2017)This paper reports an experimental campaign that aims at measuring the evolution of bridge modal properties during the passage of a vehicle. It investigates not only frequency shifts due to various vehicle positions, but ... -
Experimental and numerical studies of tubular concrete structures subjected to blast loading
(Peer reviewed; Journal article, 2021)The E39 coastal highway route along the west coast in Norway is envisioned a future without ferries. A submerged floating tube bridge built in concrete has been suggested as a means of crossing wide and deep fjords, and ... -
Experimental and numerical studies on the structural response of normal strength concrete slabs subjected to blast loading
(Journal article; Peer reviewed, 2018)To assess the blast performance of concrete structures, a shock tube has been used to simulate blast loading against concrete slabs of two different mixes ordered as C45/55 and C20/25. The C45/55 slabs were tested without ... -
Experimental monitoring of bridge frequency evolution during the passage of vehicles with different suspension properties
(Journal article; Peer reviewed, 2019)The natural frequencies of coupled vehicle-bridge systems change with vehicle position. These changes are generally attributed to the contribution of the additional mass of the vehicle. However, other mechanical properties ... -
Experiments and simulations of empty and sand-filled aluminum alloy panels subjected to ballistic impact
(Journal article; Peer reviewed, 2017)In this study, we use a discrete particle method in combination with finite element analysis to describe the interaction between structures and granular media during ballistic impact. By applying a discrete particle method ... -

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. ... -
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 ... -
