PROBLEM TO BE SOLVED: To provide an aseismatic reinforcing method for existing building capable of improving workability in a construction site without using a spiral reinforcement and constituting the connection part of the column-beam frame of an existing building with a framed steel brace so as to have a dynamic property equal to or more than in a conventional construction method while approaching the center of the peripheral frame of the framed steel brace to the connecting face of the column-beam frame as close as possible. SOLUTION: When the framed steel brace consisting of the steel peripheral frame and a steel brace is added to the outer surface of the column-beam frame of the existing building as the connecting face to perform an aseismatic reinforcement, an anchor bolt is driven into the connecting face of the column-beam frame. Steel plates for blocking the side surfaces of the clearance with the connecting face of the column-beam frame are fixed and mounted by bolts passed in positions avoiding the interference with the anchor bolt, the framed steel brace is positioned to the connecting position of the column-beam frame. Mortar or the like is filled in the space enclosed by the peripheral frame, the steel plates, and the connecting face of the column-beam frame.
