系统介绍了国内外各类抗震设计规范和导则中关于设计地震动时程方面的规定。分别从时程分析范围、时程组数以及天然时程所占比例、设计地震动时程的峰值和反应谱特性、设计地震动时程的持时特性以及设计地震动时程的相关性等5个方面，对比了不同行业抗震设计规范中关于地震动时程相关规定的异同。以我国现行《建筑抗震设计规范》为例，给出了满足相关要求的设计地震动时程，并针对设计地震动时程确定过程中需要关注的问题进行了讨论，以期为我国地震安全性评价工作中设计反应的确定谱提供参考。

The codes of various types of seismic design in China and abroad are introduced. We compare the range of the time history analysis,the number of time history groups and the ratio of groups of natural history,the peak value of the design ground motions and the characteristics of response spectrum,the duration and correlation of the design ground motions,the similarities and differences of seismic design codes about ground motion time history. In China's current “Code for Seismic Design of Buildings” is given as an example,and meets the requirements of the relevant design ground motion time history. Some problems of the design ground motion time history which need paying attention to are also discussed in order to provide references for determining the design response spectrum for seismic safety evaluation in China.
