Based on the actual project, this paper analyzes the seismic behavior of a 12-layer pure reinforced concrete frame, a reinforced concrete frame with steel pipe support and a reinforced concrete frame structure with concrete-filled steel tube supported by SAP2000. The results show that in the pure frame structure, Setting the hinged support can effectively improve the lateral stiffness of the structure, reduce the horizontal displacement of the structure, increase the energy dissipation capacity and seismic performance of the structure, and play a multi-channel fortification effect.
