FULL-SCALE CYCLIC DYNAMIC LATERAL PILE RESPONSES

In the design of vertical piles subjected to lateral dynamic loads, the lateral soil resistance is often represented as a series of discrete springs, each with a nonlinear resistance-deflection p-y curve. Owing to the lack of dynamic test data, it is common to use static load results, even for dynamic loading. The results from a recent full-scale cyclic dynamic pile test series in sand have been reduced to yield dynamic p-y curves and indicate that the current oil industry recommendations overestimate the dynamic lateral resistance, especially at large deflection levels. Strain-softening, partial liquefaction, and gapping effects were observed. Variations in dynamic stiffness and damping capacity appear more dependent on nonlinear behavior than on the frequency of excitation.
