Abstract
In this paper, the stochastic distribution of steel fiber in concrete beam is realized by using MATLAB modeling software. Firstly, MATLAB software is used to establish random distribution of steel fibers of different number, length and position, and the steel fiber model is assembled in an embedded way with the concrete model. Then the ABAQUS software is used to carry out the three point bending monotonic loading test on the model, and the stress curves and deflection curves of different steel fiber concrete are obtained. The effect of steel fiber on tensile and crack resistance in concrete is analyzed. The effect of volume, length and location of steel fiber on stress, strain and deflection of concrete beam is studied. The results show that the increase of the volume fraction can decrease the deflection and increase the tensile strength of the material, while the length has no significant effect. The distribution can significantly affect the efficiency of the fiber.
