Abstract:
In this paper, a newly developed micromechanical model has been implemented to predict the concrete response under shear and compression loading. Model predictions for shear loading support the hypothesis that, at the microlevel, cracks propagate under tensile mode. The model captures most of the phenomena associated with compressive loading qualitatively. However, the compressive strain at the ultimate load is underestimated. Three-dimensional analysis is needed to capture the compressive loading quantitatively.
