A comparison between laser, scanning, photogrammetry and infrared scanning to create 3D digital models of existing concrete bridges
(Chapter, 2020)Routine bridge inspections usually consist of visual observations. These inspections are time-consuming and subjective. There is a need to identify new inspection techniques for infrastructure that reduce traffic disturbance, ... -
A Note on Remote Temperature Measurements with DS18B20 Digital Sensors
(Chapter, 2020)Digital temperature sensors provide an attractive means to conveniently record ice and water temperatures in remote locations. Unlike conventional analogue techniques, a digital sensor performs a physical measurement, ... -
Corrosion-free concrete structures by the use of FRP (Fibre reinforced Polymers)
(Chapter, 2022)Fibre reinforced polymers may be suggested as a solution to one of the major durability problems with reinforced concrete; the corrosion of the internal steel reinforcement. The durability of fibre reinforced polymers, ... -
Ice Formation in Norwegian Fjords – Findings from the 2018 - 2019 Field Season
(Chapter, 2020)Understanding ice conditions in fjords is imperative to ensure safe operations and to protect the surrounding environment. Seven fjords in northern Norway were visited in March 2019, six with significant ice cover. In each ... -
Influence of concrete’s mechanical properties on the cracking of concrete dams
(Chapter, 2021)Analytical methods of structural stability assessment of concrete dams are often too simple and thus conservative in their predictions.Without the actual foundation geometry, capacity for some rigid body failure modes are ... -
Influence of large-scale asperities on the stability of concrete dams
(Chapter, 2022)For concrete dams founded on rock, there are only a few options in the common analysis methods to account for large‐scale asperities. However, previous research alludes that they have a significant impact on the behaviour ... -
Non-destructive testing of prestressed concrete bridges - Experiments from field test
(Chapter, 2022)Most of the structures in the transport infrastructure are built of reinforced concrete, and many of our large bridges are built of prestressed concrete. A large part of these were built before 1980, and could theoretically ... -
Numerical analysis of ice loads on Taraldsvikfossen dam
(Chapter, 2020)Static ice loads (ice actions) are a key design parameter for dams in cold climates. Since 2012,ice stresses have been measured at Taraldsvikfossen reservoir located in Narvik, Norway. Similar to earlier observations in ... -
Physical and mechanical properties of ice from a refrozen ship channel ice in Bay of Bothnia
(Chapter, 2020)Winter navigation in the North Sea is expanding with respect to vessel size and traffic volume. Icebreakers create routes for ice-going vessels by breaking the level ice cover. Repeated vessel passages in the fairways and ... -
Remote bridge inspection using optical methods
(Chapter, 2022)Routine bridge inspections usually consist of visual observations. These inspections are time-consuming and subjective. There is a need to identify new inspection techniques for infrastructure that reduce traffic disturbance, ... -
Static ice loads on a dam in a small Norwegian reservoir
(Chapter, 2020)Ice loads on a concrete dam have been calculated from stress measurements in Taraldsvikfossen Reservoir, a small reservoir in Narvik, Norway, during three winter seasons. Ice thickness was in the range of 0.5 to 1.0 m, and ... -
Wireless monitoring for assessment of concrete railway bridges - Experiences from field tests
(Chapter, 2022)This paper focus on assessment on a prestressed three span concrete box bridge by the use of a wireless monitoring system in combination with visual inspection. The bridge is located in the very north of Sweden, in Abisko. ...
