The long-term behavior of cracked fiber reinforced concrete is still poorly understood, and the interaction between fibers and matrix is of high importance. This paper presents the results of a numerical investigation into the creep of two types of polypropylene fiber reinforced concrete under sustained uniaxial tensile loading with discrete fiber modeling. The material models are calibrated on an extensive experimental program, comprising both short-term and creep tests. The influence of the fiber dispersion is statistically assessed in a Monte-Carlo analysis. The numerical results are compared against the experimental data.The results predict no structural failure after 50 years under load. The creep of the considered FRC is mainly an SLS problem, rather than a ULS issue. The two-phased modeling approach predicts low fiber load ratios, amounting to only 10% of the tensile strength, but bending moments at the crack planes greatly increase the local stresses. The fiber stress is mainly determined by the embedded angle of the fiber, rather than the embedded length or the fiber’s proximity to other fibers. Finally, it is shown that increasing the number of fibers decreases the final creep crack width, with diminishing effects at higher number of fibers crossing the crack.
