In this study, the seismic retrofitting effect of existing frame was evaluated. The strength and energy dissipation capacities of three reinforcement methods were evaluated based on the existing literatures. In the case of strength and energy dissipation capacity, it was evaluated that reinforcing effect of specimen reinforced with damper by installing K brace inside the frame was excellent. Also, it was evaluated that there is an effect of seismic reinforcement in the external retrofitting case. Therefore, proper seismic retrofit planning is expected to ensure the seismic safety of buildings.
