摘　　要：本文研究了抗震设计反应谱转时程的方法．通过对已有实测地震加速度记录的调整，获得满足工程结构抗震分析的地震动时程。首先，对国内外最具代表性的两种谱转时程算法进行了介绍，即频域调幅法和时域叠加法。随后将这两种算法的核心内容编入到源程序中，并对其计算结果进行评价。最后，对这两种算法的优缺点及适用性进行了讨论。The generation of artificial ground motions compatible with design response spectra is pre- sented in this paper. By adjusting the record accelerograms, the aceelerograms compatible with seismic design can be obtained. Two methods for adjusting accelerograms are introduced, i.e. frequency domain and time domain methods. Then these two methods are incorporated in a new computer program. The re- sults of these two methods have been reviewed. Finally, advantages, disadvantages and applicability of these two methods have been discussed.
