N2 - In this paper, a simplified method is proposed to predict the residual displacement where it is approximated by the point where a line connecting two displacement peaks in positive and negative domains of load-deflection curves crosses the abscissa. The accuracy of predicted residual displacement is much improved when the 3rd displacement peak is taken into account in addition to the 1st and 2nd displacement peaks. The proposed method is further extended and applied to the conventional capacity spectrum method to predict peak displacements. It is revealed that the method can successfully predict the residual displacements and enhance the conventional capacity spectrum method.
