Abstract
The ultimate and serviceability limit states design of certain structures based on pile foundations
by horizontal forces often require a detailed analysis of the behavior of the pile/soil system against
a lateral loading, the most commonly used approach being the concept of P-Y load-transfer curves.
These latter are empirically defined on the basis of the interpretation of geotechnical tests either
in the laboratory or in situ.
The thesis presents a database of a full-size single prestressed concrete pile were subjected to a
static lateral loading. The foundation consisted of sand overlying a partially cemented sand at the
Roosevelt Bridge replacement, Stuart, Fla. Standard penetration tests (SPT), cone penetration tests
(CPT), DMT, and PMT in-situ tests plus laboratory shear tests were used to establish the soil
profile and P-Y curves. Subsequent to testing, the strain gauges and inclinometer data were
reduced to "measured" P-Y curves.
Afterwards, the design of pile foundation submitted to lateral loads was the fifteen P-Y curvesbased from laboratory geotechnical tests and in situ tests presented in the piles literature, by
software SPULL (Single Pile Under Lateral Loads).
Finally, the predictive capability of such to choose the best method was demonstrated by
comparing the predicted pile head deflections to those measured during full-scale loading test of
isolated pile.
Keywords: Pile, Lateral loading, Displacement, P-Y curves, Horizontal loading test.
