Ultra-high-performance concrete (UHPC) is a new generation of cementitious materials with exceptional mechanical properties. In the study, the effects of the type and content of different microfibers on the mechanical performance of reinforced concrete (RC) beams were determined using finite element analysis (FEA) with Abaqus software. The cross-sectional stresses and using finite element analysis (FEA) with Abaqus software. The cross-sectional stresses and deflection of beams with UHPC produced with aramid, basalt and steel (1.0 and 2.0 % content) microfibers were assessed. The parametric data of the FEA model were defined on the basis of experimentally evaluated results of small-scale specimens. The compressive and tensile strength of the UHPC with these fibers was performed. Although the small-scale results indicate an improvement in the tensile behavior of fiber-reinforced UHPC and a negligible influence of the fiber content on the compressive behavior, the numerical results show that the use of fibers has no significant effect on the mechanical behavior of the beam (i.e., its ultimate state). The fibers increase the beam's elastic performance but have little effect on its plastic behavior. Except for 2% of steel fibers, UHPC can reduce the mechanical capacity of a beam.
