The total energy input into a structure exerted by an earthquake is mainly governed by the total mass and the effective period of the structures. The effective period of elastic structures is their fundamental natural periods. When the structure is plastified, the structure is softened and thus the effective period of structure is elongated by the plastification of structure. The influence of the plastification on the effective period is specified by the type of the restoring force characteristics of the plastified element, the extent of plastification and the pattern of distribution of plastification. In this paper, effective periods are dealt with generally by using various types of restoring force characteristics. Obtained formulae are verified their applicability by direct response analyses.
