Abstract: A method for retrofitting a reinforced concrete column by compressing a reinforcing plate including a steel plate using an external pressure is provided. The reinforcing plate is compressed to double-layer or more, that is, multi-layer in due order, on the reinforced concrete column. Accordingly, since a workability of the retrofit is excellent and since the reinforcing plate is easily compressed on the surface of the reinforced concrete column by a small lateral pressure, sufficiently the reinforced concrete column could be reinforced. Besides, a compressive strength of the reinforced concrete column could be increased. In addition, the flexibility of the reinforcing plate and the energy absorption force of the reinforcing plate could be increased.
