As the frequency and scale of earthquakes in Korea increase, the government has enacted the risk assessment of earthquake-damaged buildings to quickly respond to earthquakes and prevent the spread of earthquake damage. Among the earthquake damage risk assessment contents, the risk of vertical structural members, such as columns and walls, is evaluated according to the damage assessment criteria for damage occurring on the surface of the member by structural type. Currently, the domestic damage evaluation standard of reinforced concrete(RC) wall members borrowed from Japan's damage evaluation standard, and there is insufficient reflection of the structural characteristics of domestic RC wall members such as piloti buildings and non-seismic details. Therefore, in this paper, based on the test results of RC wall members with different aspect ratios subjected to eccentric axial force, qualitative and quantitative damage evaluation criteria for wall members were derived. Specifically, the damage level of the wall member was divided into 5 stages, and qualitative evaluation criteria based on the visible damage conditions such as cracks, crushing and spalling of covered concrete, exposure, buckling and fracture of rebara, etc for each damage level and quantitative evaluation criteria based on the maximum residual crack width were derived. The damage evaluation criteria derived in this paper showed that some qualitative and quantitative evaluation criteria were smaller at the same level of damage compared to the existing domestic damage evaluation criteria.
