Abstract: Based on the experiments of concrete floor slabs strengthened by embedded reinforcement method, combined with numerical simulations and analysis, the study explored the mechanical properties of reinforced concrete floor slabs under bending conditions. The feasibility of reinforcing floor slabs using the embedded reinforcement method was validated. Additionally, the study investigated the influence of different groove widths, embedding materials, original concrete strength grades, and reinforcement configurations on the mechanical properties of reinforced concrete slab elements.The results demonstrated that the combined action of rebars embedded using the embedded reinfocement method and concrete could achieve the same effect as embedded rebars. The size of the groove width, original concrete strength grade and the end configurations had minimal impact on the reinforcement effect of embedded reinforcement method. When high-strength grouting material was used as the embedding material, the bearing performance became closer to that of ordinary components, while offering economic and durable advantages compared to epoxy materials.
