Because the seismic performance of steel reinforced concrete (SRC) members are usually different from that of common reinforced concrete members, a modified Park-Ang damage model for SRC members is proposed in this paper. The combination coefficient of the modified damage model is derived using the related experimental results of SRC columns. Then, a formula is developed to describe the relationship between the coefficient and the parameters of the SRC columns such as the axial load ratio, steel ratio and slenderness radio. The results indicate that at the failure state of the SRC members, the modified damage index has a mean value close to 1.0 and limited scatter. The damage response of SRC members can be better represented by the modified damage model. Finally, based on the features of the skeleton curves and related research on performance classification of SRC members, the damage indexes at the principle damage states are calculated using the modified model.
