000009716 520__ $$2eng$$aBy the geotechnical criterion of Vs30≥500m/s, 260 horizontal recordings are selected from the NGA (next generation attenuation) database, and the new attenuation relations about the moment magnitude and epicentral distance are obtained by regression analysis. The predictions fit better to the observations and generally agree with the newest researches of NGA（Boore & Atkinson，Chiou & Youngs，Compbell & Bozorgnia，2006； Idriss，2007). It is demonstrated by comparison that in the old attenuation relationships exist the following shortcomings: 1 In the PGA (peak ground motion acceleration) attenuation relationships with distance, the prediction with M = 5 is lower, which is prone to unsafe, the prediction with M = 8 is higher, which prone to conservative, and the prediction with M = 6 or 7 is higher near the source but lower far from the source. 2 In the attenuation relationships of response spectra, the weak-and-moderate-earthquake response spectra might be under-evaluated for short periods near the source and for the whole period range far from the source, while the large-earthquake response spectra might be over-evaluated in the short-period range near the source and under-evaluated far from the source.
