Then, the power spectral density (PSD) of the acceleration at ground level is evaluated by an iterative approach according to the principle of equivalent peak acceleration. 然后,根据加速度峰值等效原则,选代计算得到地面的加速度功率谱密度曲线; - 2
The power spectral density function of ground acceleration can be described as filtered white noise applied on each support point. 地面运动加速度功率谱模型为零均值的平稳高斯过程,描述为过滤白噪声施加于支撑各点。
