| Abstract: | The actual bedrock records from major earthquake under the near-field condition,the attenuation relations conventionally used in the seismic safety assessment in China and the seismic response spectra adopted in the existing specifications of hydraulic engineering are used in the comparison with the Next Generation Attenuation(NGA)relations;in which the feasibility of applying Next Generation Attenuation(NGA)relations to seismic design of hydropower projects in China is demonstrated under the consideration ... |
