In the given site it does not always have the strong earthquake records, thus it’s very important to make ideal model for description of realistic earthquake ground motion time history matching the location condition. In this paper we used the sample records reformed by Chinese code 2001 version for seismic design of buildings as target earthquake records and made a modified discrete time-vary ARMA model. Both amplitude and frequency nonstationarities were incorporated into the model. Chi-Square verification tests were performed on the different nonstationary ARMA model. Application of these verification procedures was discussed and showed that the proposed models were able to reflect accurately the nonstationary features on real earthquake accelerogram, both the time-variation of the frequency and amplitude content. Thus we made a more efficiently simulated earthquake records matching the site’s condition are made and set up a organic connection between research and civil engineering design.
