To improve the seismic performance of traditional reinforced concrete structures, this study proposes a self-resetting steel-concrete hybrid structure. The key force for resetting is obtained through the elastic deformation of prestressed reinforcement. The seismic energy is then dissipated in stages through the sliding friction between steel beam sections and column bases, thereby reducing structural damage. The results show that the calculation errors of the peak load and initial stiffness of the research framework model are small, within 10%. The actual values of the resetting capacity of the research specimens are highly consistent with its calculated value. At the maximum displacement for energy dissipation capacity, the calculated value of one specimen is 294.12 kN·m, while the actual value is 295.18 kN·m, indicating a high level of accuracy in the research framework's calculations. When compared with traditional frame specimens, the research framework exhibits superior resetting capacity, stiffness, and energy dissipation capacity. This validates the superiority of the research method and demonstrates that the concrete structure has excellent seismic performance. Furthermore, the research method provides theoretical support and practical guidance for the application of the structural design in various engineering fields such as buildings, bridges, and tunnels.
