—Due to frost damage or insufficient vibration during construction, partial deterioration of reinforced concrete (RC) columns commonly exist in practical engineering, which would weaken the seismic behaviors of the structure. The work of strength is needed for the RC columns with deterioration. Thus, in this paper, the seismic behavior of CFRP retrofitted reinforced concrete column with partial deterioration was investigated by numerical and experimental approaches. Firstly, a numerical model was proposed to analyze seismic behavior of partially deteriorated RC columns and CFRP retrofitting columns. Then, the experiment with six specimens was carried out to validate the numerical results. It is found that the proposed numerical model can be used to analysis the seismic behaviors of CFRP retrofitted reinforced concrete column with partial deterioration.
