Challenges related to structural modelling and assessment of concrete structures affected by alkali-silica reactions
Kongshaug, Simen Sørgaard; Kanstad, Terje; Hendriks, Max; Kioumarsi, Mahdi; Markeset, Gro (Chapter, 2017)Alkali-Silica Reaction (ASR) in concrete is a chemical process between dissolved alkali and hydroxyl ions from pore solutions in the cement paste, and reactive (amorphous) silica within the aggregates. The product of the ... -
Durability and structural performance of pretensioned concrete girders in coastal climate bridges
Osmolska, Magdalena Jadwiga (Doctoral theses at NTNU;2022:372, Doctoral thesis, 2022) -
Durability of pretensioned concrete girders in coastal climate bridges: Basis for better maintenance and future design
Paciorek, Magdalena Jadwiga; Kanstad, Terje; Hendriks, Max; Hornbostel, Karla; Markeset, Gro (Peer reviewed; Journal article, 2019) -
Experimental investigation of ASR-affected concrete – The influence of uniaxial loading on the evolution of mechanical properties, expansion and damage indices
Kongshaug, Simen Sørgaard; Oseland, Oddbjørn Wathne; Kanstad, Terje; Hendriks, Max; Rodum, Eva; Markeset, Gro (Peer reviewed; Journal article, 2020)The alkali silica reaction (ASR) in concrete causes internal localized swelling and micro cracking, which result in expansion and correlated deterioration of the concrete material. The stress state of the concrete is known ... -
Inspection and Assessment of Corrosion in Pretensioned Concrete Bridge Girders Exposed to Coastal Climate
Osmolska, Magdalena Jadwiga; Hornbostel, Karla; Kanstad, Terje; Hendriks, Max; Markeset, Gro (Peer reviewed; Journal article, 2020)The most common methods for detecting chloride-induced corrosion in concrete bridges are half-cell potential (HCP) mapping, electrical resistivity (ER) measurements, and chloride concentration testing, combined with visual ... -
Load effects in reinforced concrete beam bridges affected by alkali–silica reaction—Constitutive modelling including expansion, cracking, creep and crushing
Kongshaug, Simen Sørgaard; Larssen, Rolf Magne; Hendriks, Max; Markeset, Gro; Kanstad, Terje (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 ... -
Load effects of alkali-silica reaction in reinforced concrete beam bridges - Material testing, Constitutive modelling and Numerical simulation
Kongshaug, Simen Sørgaard (Doctoral theses at NTNU;2023:20, Doctoral thesis, 2023)Alkali-silica reaction (ASR) is a deterioration process in concrete that was discovered in the mid-1930s, and which still affects concrete structures all over the world. ASR is considered a multi-scale phenomenon; it is a ... -
Numerical investigation into the effects of corrosion on the shear performance of pretensioned bridge girders with cast-in-place slabs
Osmolska, Magdalena Jadwiga; Kanstad, Terje; Hendriks, Max; Markeset, Gro (Peer reviewed; Journal article, 2022)Corrosion and shear cracking are frequently observed near supports of pretensioned bridge girders in coastal climates, so non-linear finite element analysis was used to study the effect of corrosion on shear performance ... -
The effect of reinforcement corrosion on the structural behaviour of prestressed bridges in the Norwegian coastal regions
Paciorek, Magda; Kanstad, Terje; Hendriks, Max; Kioumarsi, Mahdi; Markeset, Gro (Chapter, 2017)Prestressed concrete (PC) is one of the main structural materials used in Norway for bridge structures. Prestressed and precast concrete beams were even used for building the historical Atlantic Road, which has the status ... -
Toward identifying the ASR-induced stresses from displacement measurements and crack observations—Demonstration on a beam bridge in Norway
Kongshaug, Simen Sørgaard; Markeset, Gro; Kanstad, Terje; Hendriks, Max (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 ...
