Retracted: Analysis of Factors Affecting Ductility of Reinforced Concrete Column

In order to study the ductility of reinforced concrete columns under the influence of different parameters, six reinforced concrete column models with different design parameters were fabricated based on the pseudo-static test of large-scale reinforced concrete columns. The failure modes of reinforced concrete columns under the influence of different column height, longitudinal reinforcement ratio and chloride ion erosion were studied. The hysteresis curves and skeleton curves obtained from the test were analyzed, and the relationship between the displacement ductility of reinforced concrete columns and three influencing factors was obtained.
