Steel fiber reinforced concrete (SFRC) has some unpredictability in terms of the distribution of reinforcement within the concrete mass. Different fiber orientations and distributions, along with other factors, influence the mechanical performance of the composite material. In this work, a parametric study of the strength capacity of SFRC pipes is carried out using a bi phase material model (concrete + fibers) that considers the geometry of the fibers and their position within the concrete. The variables analyzed in the parametric study are fiber dosage and concrete class. Ideal cases of fiber orientations were also studied. In order to carry out this study, the three edge bearing test according to IRAM 11503 standard is simulated, which is implemented with a finite element software (ABAQUS©). Finally, the maximum load values obtained from the simulations are shown and an analytical method to estimate this load is proposed.
