✦ Synopsis

The general features of elastic-plastic response spectra for several accelerograms that are widely used for the design of buildings in Japan were studied in terms of the effects of the different hysteretic models used in the analyses. Large fluctuations existed in the spectra for both input ground motion and the different models. The models were classified according to their strain energy-absorbing capacities in three groups, within each of which the relevant nature of the elastic-plastic responses of the structures were similar. Finally, empirical formulae with which to estimate two measures of structural damage, the ductility factors and cumulative plastic displacement normalized by the yielding displacement, were developed for each group of hysteretic models.
