Earthquake resistance of structures depends strongly on capacity of deformation and energy dissipation. In this paper, damage assessment based on damage parameter is discussed. Damage parameter proposed by Fajfar is relatively stable for natural periods and yielding forces. By using the damage parameter, response ductility factors during strong earthquakes and necessary yielding forces are estimated from the ultimate allowable ductility factor under monotonic loading, the level of damage and the amount of input energy. This study shows a possibility of developing a design method which permits the designer to choose acceptable level of structural damage explicitly. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
