摘要

根据强地面运动加速度数据,采用经验地震动衰减关系公式,利用回归统计分析的方法,研究竖向和水平向加速度反应谱的关系。统计分析结果表明竖向地震动与水平向地震动的关系比较复杂,不同周期竖向与水平向加速度反应谱的比值受震级和震中距的影响不同。用水平向加速度反应谱按简单的系数折算成竖向加速度反应谱的做法应慎重。
Based on the strong ground motion data, we adopt empirical attenuation relationships and utilize regression statistical analysis method to study the relations between vertical and horizontal acceleration response spectra. The result shows that the relation between vertical and horizontal ground motion is comparatively intricate. It is various that the spectra ratio of vertical and horizontal acceleration response spectra at different periods affected by the earthquake magnitude and distance. Therefore, the modus is not available that the vertical component of the ground motion is converted from its horizontal component by a simple coefficient.
