PROBLEM TO BE SOLVED: To provide a seismically strengthening method for a reinforced concrete structure, which is implemented easily and in a short construction period, and achieves sufficient improvement in the shearing strength of the structure. SOLUTION: According to the method, slots 3 each having a predetermined width is formed in one surface of a column 1 at a predetermined interval. Then steel plates 4 are inserted into the respective slots 3, and grout is filled in gaps each between the slot 3 and the steel plate 4. The steel plates 4 are fillet-welded 6 to a covering steel plate 5 beforehand, which is formed as a lateral shearing reinforcing member conforming to a side surface form of the column 1, and therefore the steel plates and the covering steel plate are formed in one body like theπin cross section. After mounting of the steel plates 4, 5, adhesives 7, 8 formed of an epoxy resin or the like are filled in gaps. COPYRIGHT: (C)2005,JPO&NCIPI
