Two-scale modelling of reinforced concrete deep beams: Choice of unit cell and comparison with single-scale modelling
Paper in proceedings, 2019

Two-scale and single-scale models are used to analyse the response of reinforced concrete deep beams with different reinforcement layouts. To this end, a novel approach of modelling non-uniformly reinforced structures in a multiscale manner is developed. Parameterised generation of suitable unit cells is described, and the subdivision of problem domain into regions with different substructures is presented. Three different reinforced concrete deep beams with available experimental data are analysed. Mid-span deflections are slightly underestimated by both models, while the maximum load is captured reasonably well.
