✦ Synopsis

The distortions of earthquake ground motions recorded in small instrument shelters as a result of soil-structure interaction effects are investigated by means of a theoretical parametric study. A total of 12 foundation geometries varying in basal radius, embedment depth and extension above the ground surface and a number of soil profiles including uniform and layered soil models were considered. The results obtained show significant amplification and deamplification of the free-field ground motion for sufficiently soft soils (fl< 200 m/sec) and sufficiently high frequencies (f> 20 Hz).
