INFLUENCE OF SESIMOMETER FOUNDATION,ADJACENT BUILDING AND SURFACE GROUND CONDITION ON STRONG MOTION RECORDS

摘要：

To confirm whether a seismometer placed on a special foundation can accurately record strong ground motion at the surface level, we perform analytical and experimental studies into the influence of seismometer foundations, and on the presence of an adjacent building, on the ground motion recorded by seismometers. For our experiments, we utilize an earthquake observation record produced by a multi-channel array observation system installed in a building. It is determined that the seismometer foundations examined in this study can record horizontal and vertical responses at the free ground surface with good accuracy to about 10 Hz, and that the presence of an adjacent building influenced recording to greater or lesser amounts depending on the distance from the building to the observation site, with influence decreasing as distance from the building increases.
