Research Abstract |
The purpose of this study is to develop a new regression model for the power spectral density function(PSDF) and the effective duration of input ground motions. The PSDF is expressed as that of the pseudo-acceleration response of a single-degree-freedom system under a white noise excitation. The regression analysis for the model parameters of the PSDF and the duration are carried out by using the genetic algorithm and the maximum likelihood method. Then, the effectiveness of the obtained regression model are investigated and demonstrated in various applications.
