NONDETERMINISTIC INELASTIC RESPONSE SPECTRA

抄録（英）：
The present study aims at generation of probabilistic inelastic response spectra using the actual probability distributions of the strength and reduction factors. These spectra consist of constant ductility, constant strength, reduction factor and acceleration spectra. Elasto-plastic and stiffness degrading hysteresis models are used to generate these spectra for two ensembles of the artificial earthquakes for different confidence levels. It is concluded that for strength and reduction factors, the extreme value type I and II distributions are within 10％ of the actual distribution upto a confidence level of 85％ beyond which the difference is 15％. The Weibull distribution does not give satisfactory results. It is shown that the elastic forces can be reduced upto a factor of 10 for confidence level of about 85%.
