Shallow and Deep Foundations under Fault Rupture Or Strong Seismic Shaking
Two topics of interest in soil–foundation–structure interaction are presented: the first refers to the consequences on shallow and deep foundations and their superstructures from a seismic fault rupture emerging directly underneath them; the second topic addresses the seismic response of tall structures resting on shallow foundations that experience uplifting and inducing large inelastic deformations in the soil. The numerical and analytical methodologies developed for each topic have been calibrated with centrifuge experiments. The outlined parametric results provide valuable insight to the respective soil–foundation interplay, and could explain qualitatively the observed behaviour in a number of case histories from recent earthquakes.
