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 [1] and recommendations by the American Petroleum Institute (API) [2]. 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. +## Downloads + +* __download a binary version__ of the latest release on https://simcenter.designsafe-ci.org/learning-tools/pile-group-application/ +* __download the source__ of latest release at https://github.com/NHERI-SimCenter/PileGroupTool/releases + +## Software class documentation + +* An (as-yet-incomplete) documentation of the code can be found at: https://nheri-simcenter.github.io/PileGroupTool/docs/index.html +* view the source on https://github.com/NHERI-SimCenter/PileGroupTool + # References: 1.
