Abstract: The article presents the study results of the stress-strain state of the steel fiber reinforced slag concrete elements. In order to determine the physical and mechanical characteristics of the fiber-reinforced concrete experiments carried out, the analysis of which yielded mathematical relationships to describe the stress-strain model in tension and compression for designs of such cementitious composites. To describe the stress-strain state modified depending offered N. I. Karpenko and C. Sujivorakul. The mathematical models used piecewise linear displacement diagrams fibers in concrete. Authors analyzed the convergence of the theoretical curves constructed using a modified formula and experimental data.

Key words: steel fiber, stress-strain model, tensile behavior, compressive behavior, stress-deformation diagram.
