Abstract
The results of a probabilistic and statistical analysis of the fatigue resistance of conventional and fibropropylene containing reinforced concrete bending elements using standard calculation methods based on limiting forces, nonlinear deformation models and experimental data of the internal resistance of composites after 50 loading cycles with an amplitude of n = 0.8 and zero asymmetry are presented. The increased strength and fatigue durability of elements with fiber-reinforced concrete, when reinforcing structures less than the boundary level, has been established. It is assumed that the introduction of polypropylene fine fibers contributes to the internal redistribution of forces in cyclic and subsequent monotonous loading.
