Abstract: The response of pile foundations to lateral loading is a crucial aspect of pile design under extreme load events. This paper compares the experimental p-y response of three heavily instrumented, large-scale foundation elements subjected to reverse-cyclic loading until failure. The three test piles were structurally unique – a reinforced concrete, a concrete-filled steel tube, and a steel pipe – all with the same 16-inch diameter and 16-foot length. The piles were tested at the University of California, Irvine (UCI) “ Soil Pit” laboratory facility under a free head condition, where poorly graded sand with a relative density of 25-30% was placed around the piles in a controlled manner. The experimental p-y curves from the 3 piles are compared to each other and to industry standard p-y curves highlighting the impacts of structural characteristics on the p-y response.
