• Abstract:
  The project deals with evaluating how well current P-y curves predict the behavior of large diameter piles subjected to monotonic lateral loading. The motivation is that current P-y curves were developed starting about 60 years ago based on lateral load tests on piles that were about 2 ft in diameter while today’s pile diameters can reach 12 ft. This significant difference in scale brings into question the application of these early P-y curves to today’s large diameter piles. In this report, the boundary between small diameter and large diameter is set arbitrarily at 5 ft.
