Study of pile foundations

Piled foundations may need to be provided when the ground lacks the stiffness or strength required under the design loads. The analysis of structures resting on pile foundations is complex, particularly under dynamic loads (earthquakes, ship impact, wind, etc). In dense pile groups, the interaction between adjacent piles through the intervening ground has important effects on the global dynamics.

Principia has carried out dynamic analyses of this type for many major structures, such as nuclear power plants, storage tanks for liquefied natural gas, large bridges, petrochemical plants, etc.
