Article Preview

With the continuous research in earthquake engineering, great advances have been made in the theoretical research of ground motion attenuation. A lot of new achievements and views [1,2,3] provide the theoretical basis for the improvement of the ground motion attenuation experience models and the parameter estimation. Additionally, it provides a good environment for deeper study on the ground motion attenuation by the increase of strong motion records and the improvement of pertinent information. In this paper, the improved two-step method is put forward, and the regressed ground motion attenuation coefficients are obtained by the improved models and analysis method. This method not only considers the correlation of magnitude and distance, but also makes the regression coefficients more stable. The results can better show the characteristics of the ground motion attenuation.
