This invention discloses a precast reinforced concrete frame column and a frame structure, including a frame column body, an outer steel pipe, a steel end structure, and a steel connecting bracket. Based on the connection position of the external beam on the frame column body, the column reinforcement cage has an inward-facing annular groove. The outer steel pipe is fitted outside the annular groove of the column reinforcement cage, with its outer wall flush with the outer wall of the column concrete body. The steel end structure is embedded within the column concrete body. Adjacent frame columns are fixedly connected via the steel end structure. The steel connecting bracket is fixed between the outer steel pipe and the external beam. The frame structure includes precast reinforced concrete frame columns and main beams. Corresponding steel connecting brackets are provided on the outer wall of the outer steel pipe of the precast reinforced concrete frame column. The end of the main beam is fixed to the other end of the steel connecting bracket. This invention simplifies the structure and construction process of the frame columns, main beams, and secondary beams, reduces steel usage, and improves construction efficiency.
