PROBLEM TO BE SOLVED: To greatly increase the shear capacity without reducing the convenience of an existing building. SOLUTION: A steel reinforcement frame 10 which is excellent in rigidity and strength and consists of a reinforcement column 11 and a reinforcement beam 12 corresponding to an existing column 2 and an existing beam 3 on the outer periphery is constructed on the outer side of an existing building 1 formed of reinforced concrete or steel framed reinforced concrete by bringing the reinforcement column 11 and the reinforcement beam 12 close to the existing column 2 and the existing beam 3. A large number of anchors b1 , b2 are implanted in the existing column 2 and the existing beam 3 corresponding to the reinforcement column 11 and the reinforcement beam 12, the reinforcement column 11 is connected to the existing column 2 using the anchors b2 , and the reinforcement beam 12 is connected to the existing beam 3 using the anchors b1 . The strength of the reinforcement frame 10 is increased by increasing the rigidity and strength of the reinforcement beam of the reinforcement frame 10, the strength is added to the existing building, and its aseismatic property is increased thereby.
