Notes:
The hysteretic energy is an important parameter to measure the plastic cumulative damageof structures during earthquake. In this paper, with a great number of ground motions collected in the1999 Chi-Chi, Taiwan, earthquake, the main features of constant-ductility hysteretic energy spectra isanalyzed. And the effects of site condition, structural period, ductility level, damping on hystereticenergy are investigated. It is concluded that for a given period, spectra decrease with ductility ratioincreases. And as the ductility ratio increase, the spectra will be closer. In the short-period region(about less than 0.8s), spectra are strongly dependent on the structural period. In the long-periodregion, spectra tend to be constant. The limiting period depends on the ductility ratio and the local siteconditions. The damping has similar effect on spectra for all the structural period regardless ductilityratio
