Ductility forewarns the failure and enables a structure to undergo large deformation while sustaining load carrying capacity and dissipate energy in an earthquake event. Considering recent advances in energy-based seismic design approach, presenting a novel energy-based ductility design approach for nominal ductility design of VHSC (> 100 MPa) columns while considering the higher plastic energy within the VHSC columns is the focus of the study. In this paper, an accurate program to predict analytical full-range moment-curvature relation using appropriate stress-strain behavior of constitutive materials is used to predict the energy-based and curvature ductility of rectangular VHSC columns in..
