PROBLEM TO BE SOLVED: To enable earthquake resistant reinforcement in response to the strength of a column without impairing the outside appearance of an existing building by arranging and reinforcing a plate-like earthquake resistant member continuously providing a low yield point steel material and a mild steel material in parallel with the column. SOLUTION: In the reinforced concrete-made existing building, a reinforced concrete-made building frame increasing part 45 is formed on the lower part of a veranda 41 projected from a beam 40 to the outside, a PC steel rod 16 is inserted from both the sides of the column 42, an anchoring member 15 is tightened and welded with pressure on a joining part between the beam 40 and the column 42, and an earthquake resistant reinforcing member 10 is welded on the anchoring member 15. The earthquake resistant reinforcing member 10 continuously provides and forms a normal steel panel 11 vertically of a low yield point steel panel 12, and a horizontal rib is provided to give bending rigidity. The width and height of the low yield point steel panel 12 are adjusted in response to the strength of the column 42, the normal steel panel 11 is connected by a joint material 13 in response to story height, and the height of the earthquake resistant reinforcing member 10 is adjusted. Thereby the column 42 is reinforced to enable earthquake resistant reinforcing without impairing the outside appearance of the building.
