Theoretical investigation of fiber-reinforced concrete beams dispersely reinforced with basalt and steel fibers

Abstract

In this study, the maximum flexural load-bearing capacity of steel and basalt fiber-reinforced concrete beams was investigated through theoretical calculations. The ultimate bending moments of beams reinforced with different proportions of steel and basalt fiber mixtures were analyzed in detail. The theoretical results showed that the beam reinforced with steel fibers demonstrated the highest ultimate bending moment, confirming it as the most efficient option in terms of load-bearing capacity. At the same time, hybrid fiber-reinforced beams provided an optimal balance between load capacity and deformation resistance. The findings indicate that the proportion and dispersion of fibers have a significant influence on the mechanical behavior of beams under bending, and theoretically confirm the potential for designing and optimizing new types of fiber-reinforced concrete structures using a combination of steel and basalt fibers.
