A quantification of the modelling uncertainty of non-linear finite element analyses of large concrete structures
Engen, Morten; Hendriks, Max; Kohler, Jochen; Øverli, Jan Arve; Åldstedt, Erik (Journal article; Peer reviewed, 2017)In order to make non-linear finite element analyses applicable during assessment of the global resistance of large concrete structures, there is need for a solution strategy with a low modelling uncertainty. A solution ... -
Non-linear finite element analyses applicable for the design of large reinforced concrete structures
Engen, Morten; Hendriks, Max; Øverli, Jan Arve; Åldstedt, Erik (Journal article; Peer reviewed, 2017)In order to make non-linear finite element analyses applicable during assessments of the ultimate load capacity or the structural reliability of large reinforced concrete structures, there is need for an efficient solution ... -
Predictive strength of ready-mixed concrete: Exemplified using data from the Norwegian market
Engen, Morten; Hendriks, Max; Kohler, Jochen; Øverli, Jan Arve; Åldstedt, Erik; Mørtsell, Ernst; Sæter, Øystein; Vigre, R (Journal article; Peer reviewed, 2018)A hierarchical model for the variability of material properties in ready‐mixed concrete is formulated. The model distinguishes between variation on the batch, recipe, plant, producer, durability class, strength class, and ...
