摘要

One of the principle shortcomings with lateral analysis of large diameter pile foundations is the reliance on beams on elastic foundation. Within numerical modeling, the fundamental nature of the interactions of steel to concrete, steel to soil, and concrete to soil are often difficult to constrain in non-linearity. Modeling with a simplified cracked modulus for the pile does not capture the path from linearity to non-linearity. The progressive occurrence of concrete cracking with yielding rebar and steel casing, with concrete crushing results in pile non-linearly under bending. Furthermore, the interaction of the structural materials and soil beyond Winkler relationships is desirable so that soil can flow around the foundation and assessment of stress changes in the field to affect adjacent facilities. For large displacement problems the ability of the shaft to rotate, bend, shear, twist, and "oval" under complex lateral loads is important. A numerical methodology that addresses these shortcomings was developed. This paper briefly presents the method along with comparison with conventional methods.
