In this paper, elastic-plastic dynamic response analysis of one story vibrational models with eccentricity are carried out From results of analyses, it was concluded that in eccentric structures having the optimum strength distribution which can be obtained by means of modal analysis no damage concentration occurs in specific structual planes. In structures having general (not optimum) strength distribution, damage concentration can be estimated by applying the parameter pti which indicates the defference between the actual strength distribution of the structure and its optimum strength distribution.
