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:

  • soil structure (up to 3 layers of variable thickness) and soil properties
  • position of the ground water table
  • pile stiffness, embedment length, connection type to the pile cap
  • number of piles in the group (one to three piles)
  • the applied horizontal force at the pile cap (push-over analysis)

Presented results include:

  • lateral displacement of all piles
  • moment and shear diagrams for each
  • vertical soil stresses
  • ultimate strength and stiffness parameters for the employed p-y springs

New in this release:

  • extension to lateral and axial loads, as well as moment on pile cap
  • push-over and pull-out analysis
  • lateral spreading/liquefaction analysis through quasi-static soil motion profile
  • additional results plots: axial load and displacement, t-z spring parameters
  • save to and load from file (JSON)
  • export OpenSees source file for current system and loads
  • switch from QCP to Qwt
  • switch from GPL3 to BSD license
  • performance enhancements for a more fluent user experience

The SimCenter is supported by a grant from the National Science Foundation (#1612843)
