Abstract
In this paper, the influence of different kinds of fiber on the mid-span bending moment and deflection of the regenerated concrete beam under the initial cracking and yielding state is studied by ANSYS finite element simulation analysis. The results show that different kinds of fibers have little influence on the mid-span bending moment of the regenerated aggregate concrete beam at the initial cracking, and have a great influence on the deflection value at the initial cracking, among which the reinforced effect is obtained in the group mixed with steel fiber. The mid-span bending moment and deflection of the trabeculae at the yield of the trabeculae are reduced by the addition of different kinds of fibers.
