The invention discloses a steel column base structure with double replaceable energy-dissipation connection and a design method thereof. The steel column base structure comprises a steel column, a steel column base, a double replaceable energy-dissipation component and a ground beam. The steel column is connected to the steel column base through the double replaceable energy dissipation component, and the steel column base is connected to the ground beam through the high-strength bolt rod. The steel column and the steel column base are non-replaceable components, the dual replaceable energy dissipation component comprises an energy dissipation steel plate and an energy dissipation steel bar, and the energy dissipation steel plate serves as a first defense line to dissipate energy of the input structure; when the energy dissipation steel plate generates plastic deformation, the energy dissipation steel bar is still in an elastic state and serves as a second defense line to increase the safety redundancy of the
