This study serves to provide a thorough and detailed comparison between numerous available identification models used to ascertain the seismic failure modes and failure characteristics of reinforced concrete columns. The relevance between seismic failure modes of columns and their corresponding influencing factors such as transverse reinforcement ratio, longitudinal reinforcement ratio, aspect ratio, axial load ratio, shear and flexural capacity as well as the concrete compressive and tensile strength was scrutinized with reference to the pool of existing test column specimens and experimental observations. Prediction accuracies of column failure modes namely flexure, flexureshear and shear based on existing prediction models are evaluated. Following that, potential improvements of these prediction models are explored. Probabilistic-based seismic design and assessment of reinforced concrete columns can be made possible using the insights derived from the model development processes.
