To examine site dependence and evaluate the applicability of methods for site analysis of far-field ground motions, the authors present an analysis of the frequency content estimated with different methods using strong ground motions recorded at twelve far-field stations in Shandong Province during the Wenchuan earthquake. The results show that: predominant periods obtained by Fourier amplitude spectra, response spectra and H/V ratio methods are all evidently larger than site dominant periods, and different methods yield different periods, which mainly reflect the frequency content of long period components.
