The SimCenter Pile-Group Tool provides a dynamic interface to study the behavior of a pile or pile-group in layered soil. It allows the user to interactively (and nearly instantly) observe the system's response to changes of the following parameters:
Presented results include:
The soil-structure system is modeled using a finite-element platform. Piles are represented by displacement based beam-column elements. Soil-structure interaction is represented laterally by p-y springs and tangentially by t-z springs. Spring properties are computed using Hansen's method  and recommendations by the American Petroleum Institute (API) . The Pile-Group Tool constructs a structurally and numerically appropriate finite-element mesh, computes spring properties from soil properties, and places spring elements accordingly. The actual simulation employs a Newton-Raphson iterative procedure to solve the governing nonlinear system of equations.
