概要	In this study, the nonlinear peak response of a retrofitted nine-storey steel reinforced concrete building with steel damper columns was analytically investigated. A steel damper column was added on the side of the exterior frame by connection joint, using mortar, anchors, and studs. The peak response was predicted using nonlinear static (pushover) analysis, the peak storey drift, and the maximum moment and shear force at the connection joint, and the results were compared with the results obtained by nonlinear time-history analysis. Thus, it was revealed that the predicted peak storey drift, the maximum shear force, and moment at the connection joint are in good agreement with the time-history analysis results. The largest shear force of the anchor in the connection joint was also evaluated and compared with the time-history analysis results.
