PileGPw is an interactive software program developed to provide the distribution of load and computation of axial deformation of the piles within a pile group. This program is based on the elastic analyses provided by Randolph and Wroth (see references) for single piles and a pile group under axial loads only.

PileGPw can analyze regularly or variably spaced piles in any group configuration as long as locations can be described by a coordinate system. The piles may be of variable diameters; however, all piles in the analysis must be of the same length. This program can provide the distribution of loads within a group with a rigid cap and also the distribution of load within a group utilizing a flexible pile cap. Pile caps other than rigid can be modeled by introducing individual pile-head settlements. This feature allows the presentation of individual pile-load differences caused by a rigid pile cap.
