Both seismological theory and macroseismic observation show that the shape of strong motion response spectrum depends mainly on magnitude,distance of epicenter and engineering site condition.since it is considered just the effect of engineering site condition and epicenter distance of only site condition to determine the characteristic period of acceleration response spectrum in the antiseismic design criterion of our country at present,the characteristic period of response spectrum determined from those critetion is different from that got from special seismic hazard analysis.

地震学理论和强震观测都表明，强震反应谱的形状主要取决于震级、震中距和场地条件。由于我国现行的各种行业建筑物抗震设计规范中对标准加速度反应谱特征周期Tg作出的规定中一般只考虑场地和震中距的影响或只考虑场地影响，因此在某些情况下，由规范所得到的反应谱特征周期与由专门的地震危险性分析所得到的结果相差较大。
