Abstract
The paper presents an analysis of dispersed reinforcement methods. Metal fibres have been used when conducting the experiment. It has been shown that the reinforcement of concrete with metal fibers can significantly increase crack resistance for structures made of fiber-reinforced concrete in comparison with similar reinforced concrete structures.It should be noted that blocking crack development and blocking the possibility of the main cracks formation is achieved in structures made of fiber-reinforced concrete due to a more uniform distribution of forces arising in concrete. The results of an experiment on the reaction of beams with dispersed reinforcement to a bending load have been presented. The calculation of stretched and bending element with dispersed and combined reinforcement has been performed. The calculation showed that the use of combined reinforcement in structures can increase their overall bearing capacity. The comparison of the calculation and experiment results has shown a showed good convergence.
