Research on random function model of strong ground motion(Ⅱ):parametric statistic and model certification

AN Zihui,LI Jie(Department of Building Engineering,Tongji University,Shanghai 200092,China)  
According to the site classification,the model parameters were divided into four classes,and the probability densities were estimated by the stochastic modeling method.Making the assumption about statistic independence,the joint probability density functions were obtained.In order to divide the probability-assigned space by a point set with cardinal number as small as possible,the number-theory method was introduced to determine the representative points of the model parameters.Substituting the represented points in the proposed random function model and performing the inverse Fourier transform yield the assembles of the stochastic accelerograms.The comparisons of the mean and standard deviation of the Fourier amplitude between the assembles of the predicted accelerograms and the counterparts of the recorded accelerograms were made,which showed that the prediction is reasonable.
