By modeling the foundation as a rigid pile-head supported by a group of deformable piles, it is the objective of this thesis is 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. A sensitivity investigation is conducted 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.Author owns copyright, except where explicitly noted.
