In order to study the feasibility of replacing part of longitudinal reinforcement with layered steel fibers, four-point bending tests were carried out on a group of ordinary recycled concrete beam and three groups of layered steel fibers recycled concrete beams. The cracking moment and ultimate moment, ductility and energy dissipation, deformation and deflection of the experimental groups with lower contents of steel fibers and higher reinforcement ratio and the experimental groups with lower reinforcement ratio and higher contents of steel fibers were compared and analyzed. The results show that it is feasible to replace some longitudinal bars with layered steel fibers when considering cracking moment, ultimate moment, elastic stage and working stage with cracks of load-deflection curve, while it is not feasible when considering ductility, energy dissipation and post-yield stage of load-deflection curve.
