Finite element analyses of confined columns are presented. Based on a confinement dependent uniaxial concrete model, the importance of the yield strengths of the stirrups and the longitudinal reinforcement bars, the spacing of the stirrups, and the configuration of the cross-section, in combination with different load eccentricities are evaluated. It was found that the spacing of the stirrups and the reinforcement configuration are of the greatest importance for the post-peak behavior. To achieve ductile structural behavior of highstrength concrete columns, a higher value of the volumetric stirrup ratio is required. However, it was found that, even for concretes currently accepted by the code, a higher ratio than that corresponding to the required maximum spacing of 15f is needed to obtain the same ductility as a concrete of grade K40.
