Piles are routinely used as foundations to support short-to-medium span bridges and buildings typically over four stories and other structures. Collapse and/or severe damage of pile-supported structures is still observed in liquefiable soils after most major earthquakes such as the 1995 Kobe earthquake (Japan), the 1999 Kocaeli earthquake (Turkey), and the 2001 Bhuj earthquake (India). The failures not only occurred in laterally spreading (sloping) ground but were also observed in level ground where no lateral spreading would be anticipated. A good discussion on the failure modes can be found in Bhattacharya and Madabhushi (2008).
The failures were often accompanied by settlement and...
