Determination of design ground motion for critical engineering project;

Study on ground motion parameters of scenario earthquake using stochastic simulation method;

Determination of design response spectrum for important structures based on scenario earthquake;

Study on scenario earthquake at Kezier Dam site in Xinjiang;

Design earthquakes in earthquake hazard prediction are discussed in detail.

To solve this problem,this paper puts forward one improved estimating method for different engineering structures by taking the structural feature period as the typical parameter based on theoretical analysis,practical experience,and then design earthquake could be estimated by main affecting potential seismic areas according to seismic hazard analysis and attenuation relation.
