This paper introduces the meso-scale modeling of fiber reinforced concrete under mixed mode fracture. Fibers and matrix are modeled separately in this model, and each fiber is randomly arranged within the specimen models. The feature of this analytical model is to evaluate fiber resistance against shear deformation across the crack plane by calculating the pullout angle and the pullout displacement of each fiber. In order to validate the modeling, fracture analysis of the speci- men with punching shear failure was conducted. It was confirmed that the proposed model can roughly simulate the failure of fiber reinforced concrete including crack patterns and load carrying capacity.
