Abstract: The lack of ductility of plain high-strength concrete (HSC) has put some strong concerns on the adequacy of HSC columns when a higher ductility of the structural member is required, as in zones of high seismicity. In this study, the numerical simulation of the ductility of HSC columns is presented. Two mathematical models representing confined concrete behavior are discussed: the Razvi and Saatcioglu and the modified Fafitis and Shah models. Monte Carlo simulation is used to generate curvature ductility statistics for different concrete compressive strengths, amount of longitunal and transversal steel, and axial load levels acting on the column. It is shown that ductility may be largely increased if adequate amounts of confining and longitudinal steel are used.
