Abstract

When assessing possible seismic impacts, the important ground motion parameters are the level and duration of seismic vibrations. Based on the earthquake records at the Petropavlovsk seismic station (Kamchatka), expressions are obtained for calculating the maximum amplitude of horizontal acceleration, the duration of the area of vibration section at a level of 0.5 of the maximum amplitude, the RMS amplitude in four frequency bands, and the boundaries of the frequency band in which the maximum accelerations are observed. The calculations used records of 75 regional earthquakes with magnitudes of 3.9−8.3.

摘要

在评估可能的地震影响时，重要的地面运动参数是地震振动的水平和持续时间。根据Petropavlovsk地震台（Kamchatka）的地震记录，获得了用于计算水平加速度的最大振幅，最大振幅为0.5的水平振动区域的持续时间，四个频率的RMS振幅的表达式。频段，以及观察到最大加速度的频段边界。计算使用了7.5−8.3级的75次区域地震的记录。
