To provide a seismically retrofitting structure which is for use in seismically retrofitting an existing reinforced concrete structure or a steel framed reinforced concrete structure mainly suffering from lack of earthquake resistance, by using a fiber sheet, wherein the overall surface of the fiber sheet making intimate contact with an earthquake resistant wall is held in a manner being combined with the earthquake resistant wall in one body, to thereby prevent the overall surface of the fiber sheet from separating from the same, and to provide a seismically retrofitting method.
According to the seismically retrofitting structure, the fiber sheet 2 is stuck at least to one surface of the earthquake resistant wall 1, and a reinforcing member 3 is bonded to a surface of the fiber sheet 2, followed by inserting binding members 4 into the earthquake resistant wall 1 to be fixed to the surface of the reinforcing member 3 via respective fixing devices 5. In this manner the earthquake resistant wall 1 is bound in an out-of-plane direction.
