Review article

There are submitted the results of experimental and theoretical studies on the calculation of the strength of steel-fiber-reinforced concrete structures under conditions of complex deformations. The article presents a review of current issues regarding the strength theory of concrete and reinforced concrete in combination with dispersed reinforcement (steel-fiber concrete). Concurrently, for each specific case of complex deformation, the main design schemes and formulas for the bearing capacity are given, as well as the adopted original methods for accounting for steel fiber concrete in the overall performance of the structure under load. The reliability of the obtained analytical expressions for the strength, as well as the reliability of the presented scientific studies, is confirmed by the results of experimental and numerical tests.
