numerical simulation model is presented for the analysis of the deformational behavior of fiber reinforced concrete. Microstructural unit elements are used to model the fiber reinforced concrete which is decomposed into fiber, matrix and interface between them. The nonlinear material properties are modeled separately for those three domains. The pullout behavior of parallel fibers at a crack surface is simulated taking into account the stiffness of the fiber.
