Abstract: The article describes the main provisions of probabilistic mathematical model to assess the reliability of bent elements, steel-reinforced dispersion-discrete fibers with a single limb at both ends («Dramix»). The authors, based on a mathematical nonlinear deformation model developed probabilistic algorithm and a computer program to assess the reliability of fiber concretes beams, flexural, taking into account physical nonlinearity of materials, which implements the method of statistical modeling. Probability calculation is to determine the statistical characteristics of strength, stiffness and fracture study design elements during a large number of statistical tests associated with modeling initial random quantities - prism strength matrix ultimate strength tensile fibers, the angle of orientation of the fibers and their incorporation. As a result, the program outputs the reliability indexes bent elements, reinforced with steel discrete fibers for strength, stiffness and fracture toughness. These figures allow us to judge about the serviceability of the study of structural elements.
Key words: probabilistic mathematical model, statistical modeling method, random variable, discrete fiber, reliability of the design element.
