Collapse of pile-supported structures is still observed in liquefiable soils after most major earthquakes causing great concerns to the earthquake geotechnical engineering community. A safe design approach would require the foundation to vibrate in the liquefied soil without exceeding yield anywhere in the pile. The excitation or the forcing function for these vibrations is predominantly due to the inertia of the superstructure. This paper analyses high quality experimental data obtained from dynamic centrifuge tests to characterize this vibration. The same problem has been analyzed analytically. Emphasis has been given to dynamic instability of piled foundations in liquefied soil.
