国内外各类抗震设计规范对设计反应谱给出了不同的计算方法，对各类反应谱不同的计算方法进行对比分析；利用世界范围内大地震时获得的数字强震仪记录，计算相应的加速度反应谱；结合结构动力学理论分析及统计分析方法，提出抗震设计反应谱统一计算公式。实际强震地震波具有高度的非平稳性，人工地震加速度时程不能直接反映实际地震加速度时程的非平稳性。为了得到与实际地震波类似的高度非平稳性且与设计反应谱兼容的地震加速度时程，以一组强震地震波为母波，得到与设计反应谱兼容的人工地震加速度时程。通过对人工地震加速度时程与实际地震波比较，发现其继承了实际地震波的非平稳性；同时人工地震加速度时程反应谱与目标设计谱具有较好的一致性。

Various domestic and foreign seismic design codes offer different calculation methods to the design re-sponse spectrum,and the different calculation methods for various types of response spectrum were compared with each other.The corresponding acceleration response spectrum were calculated employing the digital strong motion earthquake records obtained in the world range.Combined the structural dynamics with statistical analysis method,the unified calculation method of the design response spectrum was proposed.The actual strong motion earthquake waves are highly non-stationary,and in this case,the normal synthetic earthquake accelerograms cannot directly reflect the non-stationarity of the real earthquake waves.In order to get highly non-stationarity synthetic earthquake accelerograms,which are similar to the actual earthquake and compatible with the design response spectrum,this paper took 10 group earthquake waves as the parent waves to obtain the synthetic earth-quake accelerograms compatible with the design response.Through the comparison of the synthetic earthquake accelerograms and actual earthquake waves,it shows that the synthetic earthquake accelerograms inherit the non-stationarity of the actual earthquake waves,and at the same time,the response spectrum of the synthetic earth-quake accelerograms and the target design spectrum is consistent with each other.
