Abstract
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.
