The invention provides a connecting structure and a connecting method for a steel pipe column and a concrete frame. The connecting structure comprises multiple embedded parts which are embedded in the concrete frame, embedded connectors which are embedded in the concrete frame and connected to two adjacent embedded parts, and connectors which are connected to the steel pipe column and the embedded parts. According to the connecting structure, multiple embedded parts are embedded in the concrete frame, and two adjacent embedded parts are connected by the embedded connectors, so that multiple embedded parts in the concrete frame are integrated into a whole and are difficult to damage; and the connecting structure solves a problem of poor connection quality of the traditional steel pipe column and the concrete frame, so that the whole connecting structure is stable so as to met design requirements.
