A review of concrete properties under the combined effect of fatigue and corrosion from a material perspective
(Peer reviewed; Journal article, 2023)When in use, reinforced concrete bridge structures not only experience high-frequency fatigue loading caused by passing vehicles, but also suffer from the effects of a corrosive environment. In addition to fatigue damage ... -
Asset Management of Existing Concrete Bridges Using Digital Twins and BIM: a State-of-the-Art Literature Review
(Peer reviewed; Journal article, 2022)The need to optimize investments in bridge maintenance has created a demand for improved bridge management systems (BMS). Outdated practices in bridge inspection and constant advances in information technology have also ... -
Freeze-thaw damage evaluation and model creation for concrete exposed to freeze–thaw cycles at early-age
(Peer reviewed; Journal article, 2021)Concrete subjected to freeze–thaw cycles action at early-age will suffer serious physical damage, resulting in degradation of the concrete’s performance. The subsequent curing conditions after early-age freeze–thaw cycles ... -
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 ... -
Mechanical and durability properties of concrete subjected to early-age freeze–thaw cycles
(Peer reviewed; Journal article, 2021)Early-age frost damage to concrete used in winter construction or in cold environments negatively affects the development of the hydration process and the performance of the concrete, thereby reducing the service life of ... -
Post-peak behavior of concrete dams based on nonlinear finite element analyses
(Peer reviewed; Journal article, 2021)Dam failures are catastrophic events and in order to improve safety, engineers must have good tools for analysis and an understanding of the failure process. Since there are few cases of real failures in concrete dams, ... -
Prediction of Strain in Embedded Rebars for RC Member, Application of Hybrid Learning Approach
(Peer reviewed; Journal article, 2023)The aim of this study was to find strains in embedded reinforcement by monitoring surface deformations. Compared with analytical methods, application of the machine learning regression technique imparts a noteworthy reduction ... -
Probabilistic finite element analysis of failures in concrete dams with large asperities in the rock–concrete interface
(Peer reviewed; Journal article, 2023)Common analytical assessment methods for concrete dams are unlikely to predict material fracture in the dam body because of the assumption of rigid body behavior and uniform- or linear stress distribution along a predetermined ... -
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. ...
