This paper describes a procedure which is suited to the analysis of complex structural systems which are pile supported and which react to loads in a non-linear manner. The method is based on an incremental stiffness approach, and is easily adapted to almost any geometry and loading. The substructure is assumed to be either bearing or friction piling, which can be free-standing. The pile cross-section can be either circular or "H" shaped, although, with certain modifications, other forms could be presumed. The response of the piling and associated superstructure can be either elastic or inelastic, and the subgrade reactions in both the horizontal and vertical directions can take on any linear or nonlinear form. Interaction between superstructure and substructure is through families of precalculated stiffness coefficients which are functions of moment, shear, and axial thrust. Several realistic examples are considered, and for each, overall load - deformational relationships are developed. These solutions are carried well into the inelastic range of material behavior.
