Sažetak
Eurocode allows recorded acceleration time histories for representations of seismic action for design of structures. However, it does not define whether the ground motion time histories should be obtained from instruments mounted on foundations, below foundations or placed in free field. Recent laboratory experiments showed that foundation input motion may be of higher intensity and with different frequency content when compared to the motion recorded in free-field during same earthquake event. However, results obtained during a real earthquake events showed that input motions at the foundation of a structure are of similar intensity when compared to motions recorded in free-field, not far from the structure. In order to investigate the discrepancy this paper provides comparisons of signals recorded at the same time in free-field and on foundations of structures during the same earthquake event. The signals used were obtained from four different built environments experimentally tested in centrifuges and on shaking tables in Japan, Europe and Canada.
