Pile Group – Analysis of a Pile Group


(Pile Raft Foundations with a Rigid Pile Cap)

 

The program performs the analysis of pile group (pile raft foundation with a rigid pile cap) using both spring method (FEM) or analytical solution. General load acts to the centre of a pile cap. Geological environment consists of horizontal layers of soils or rocks. Both floating piles and piles fixed into the subsoil can be considered.

 

Analytical solutions

  • Analysis of vertical bearing capacity of a pile group of in cohesive soil as a rigid earth block according to FHWA standards
  • Analysis of vertical bearing capacity of a group of piles in cohesionless soil (NAVFAC DM 7.2, Effective stress, CSN 73 1002)
  • Reduction of vertical bearing capacity of a pile group (UFC 3-220-01A, La Barré, Seiler-Keeney)
  • Settlement analysis of a pile group in a cohesive soil as a settlement of substitute foundation
  • Settlement analysis of a pile group in cohesionless soil according to Poulos (load-settlement curve)

 

Spring method (FEM) – Analysis of a three-dimensional action of a group of piles

  • Analysis of rotation, deformation and displacement of a rigid pile cap
  • An arbitrary number of load cases and their combinations
  • Hinged or fixed connection between piles in a group and a rigid pile cap
  • Floating, rested or fixed piles into the foundation subsoil
  • Possibility to introduce inclined piles and general shape of a rigid pile cap
  • An automatic post-calculation of springs along the pile length piles from soil properties
  • Possibility to introduce both horizontal and vertical springs along the pile length
  • Distribution of displacements and internal forces along for each pile in a group
  • Dimensioning of a pile reinforcement according to EN 1992-1 (EC 2), BS, PN, IS, AS, ACI, GB, CSN, SNiP
