Meso-Scale Analysis Considering Effect of Fiber Inclination in Fiber Reinforced Cementitious Composites
This paper introduces meso-scale modeling of fiber reinforced cementitious composites, which can consider the effect of fiber inclination. 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 by calculating the pullout angle and the pullout displacement of each fiber. In order to investigate the effect of the pullout angle of the fibers on the load carrying capacity, fiber pullout analysis and bending analysis was conducted. It was confirmed that bending tests were more adequately represented by the modeling taking into consideration the pullout angle than by one without considering the pullout angle.
