On the basis of the results of probabilistic seismic hazard analysis,the most contributing potential seismic source zone in different periods of vibration was determined. The magnitude and epicentral distance of scenario earthquake were calculated by using the joint distribution function of magnitude-space and the related formula. And then, based on seismo-geological characteristics, causative faults and seismic activity, the specific spatial location of scenario earthquakes were determined. Finally, according to the magnitude, epicenter distance and attenuation relationship the response spectrum of scenario earthquakes were obtained. The results could directly reflect seismic hazard, and help to get the ground motion parameters of bedrock with the consideration of earthquake environment. The results can also provide some references for seismic fortification of high-rise buildings in different periods of vibration.[著者文摘] %R %U http://zgdz.eq-j.cn/zgdz/home %1 JIS Version 3.0.0
