Reinforced concrete columns are the most important structural elements that determine the ductility of the structures. The main parameters affecting the behavior of reinforced concrete columns are axial load level, shear span, percent of longitudinal reinforcement and percent of transverse reinforcement. In the context of this study, seismic analysis of reinforced concrete columns with various features modeled in the Seismostruct program was performed. Analytical models were verified by comparing the analytical results with the experimental results. When the results of analytical models are examined, it can be seen that the residual drift ratio of reinforced concrete columns can be used to characterize the damage occurred in the structure after earthquake or loading. In addition, the performance level of the reinforced concrete columns according to the residual drift ratio is defined in FEMA356. As a result of this study, the analytical equation that calculates the displacement capacity of the reinforced concrete columns and residual drift ratio of the reinforced concrete columns at the ultimate displacement limit is proposed
