Through the three-point bending test on the specimens of steel fiber reinforced high strength concrete (SFHSC) and plain high strength concrete (HSC) with the size of 100 mm×100 mm×515 mm, the effects of influencing factors including the fiber volume fraction (ρf) and relative notch depth (a/W) upon the fracture energy and the work of applied force (gravity and external force) were studied. The results show that the effect of ρf upon the fracture energy is more obvious; the variation tendencies for the increment ratio of the fracture energy and that of the work of applied force are different under different factors; the fracture energy is dependent on the work of external force. Based on the test results, the formula was established for calculating the fracture energy.

The paper presents the results of tests for flexural tensile strength (fct,fl) and fracture energy (Gf) in a three-point bending test of prismatic beams with notches, which were made of steel fibre reinforced high-strength concrete (SFRHSC). The registration of the conventional force–displacement (F–δ) relationship and unconventional force-crack tip opening displacement (CTOD) relationship was made. On the basis of the obtained test results, estimations of parameters fct,fl and Gf in the function of fibre reinforcement ratio were carried out. The obtained results were applied to building and validating a numerical model with the use of the finite element method (FEM). A non-linear concrete damaged plasticity model CDP was used for the description of the concrete. The obtained FEM results were compared with the experimental ones that were based on the assumed criteria. The usefulness of the flexural tensile strength and fracture energy parameters for defining the linear form of weakening of the SFRHSC material under tension, was confirmed. Own equations for estimating the flexural tensile strength and fracture energy of SFRHSC, as well as for approximating deflections (δ) of SFRHSC beams as the function of crack tip opening displacement (CTOD) instead of crack mouth opening displacement (CMOD), were proposed.
