| 摘 要： | 本文订正了前文1]公式中的符号差错，重新计算了犁阻尼加速度反应谱，另外又计算了速度谱和位移谱，并与相应的粘性阻尼谱作了比较，取得了一定的认识。现有计算结果显示，复阻尼速度谱和位移谱有一定特点，在中长周期和长周期部分可比相应的粘性阻尼谱高出10％左右。

| Abstract: | In this paper, the sign errors in the previous paper1] are corrected and the renewed complex damping acceleration spectra of some representative earthquake records are provided. In addition, the velocity and displacement spectra are also calculated. The results show that in comparison with the corresponding viscous damping response spectra, there are not obvious changes in the complex damping acceleration spectra, but the values of velocity and displacement spectra in the range of middle and long periods may exceed by 10%. |
