Earthquake resistance of structures depends on capacity of deformation and energy dissipation. In this paper, damage assessment is based on damage parameter, which is a function of dissipated hysteretic energy and maximum displacement. Dissipated hysteretic energy is influenced by predominant periods of earthquakes. However, damage parameter is relatively stable for natural periods, yielding forces and type of input motions for the structures. By using this damage parameter, ductility factors corresponding to damage models during strong earthquakes are estimated with given ultimate ductility factor under monotonic loading and damage level. This study shows a possibility of developing a design method which permits a designer to choose acceptable level of structural damage explicitly.
