The peak acceleration attenuation relations based on side classified criterion in current seismic design code

The strong motion records with boring data classified site category according to the Code for Seismic Design of Buildings (GB 50011-2001) are adopted to analyze attenuation relations of peak ground acceleration in three kind of side by statistic method. The comparison of the attenuation relation in the paper with other analyses is made on rock site, the results shows that it is feasible that the strong motion records in different countries and zones are used to analyze the earthquake parameters on appointed zone. The attenuation relations give the suggestion about the PGA level on different kind of site (especially on soil site) in China.
