A three-dimensional finite element model was developed to investigate the non-linear behavior of single piles embedded in layered soil deposits under static and dynamic lateral loading. Emphasis was placed on evaluating the effects of gap formation between the pile and the soil on the response characteristics such as load-deflection relations, distribution of bending moments, lateral deflections, and soil resistance at various depths under static lateral loading. In addition, the gap effects on the frequency response of circular pipe pile supporting a rigid cap-mass superstructure under dynamic lateral loading were studied. The output of the non-linear analysis was confirmed using existing results of full-scale experimental data.
