Modeling the foundation as a rigid pile head supported by a group of piles, it is the objective of this paper to study its characteristic resistance curve; in this regard several pushover analyses of a single pile under kinematic constraint at the point of connection with the overbearing pile-head were conducted, in order to observe the intensity and influence of the soil-pile interaction on the superstructure deformation demands when excited by ground motion events of increasing intensity. Parametric investigation conducted is intended to support the development of quantitative models for the coordinates of the milestone points of the resistance curve in terms of the important design variables (soil profile, pile aspect ratio, etc.) which could then be scaled up to integrate into the resistance curve of a complete pile-group. In the study an example bridge overpass of the Ontario Highway system is used in order to maintain relevance to the Canadian practice.
