PileGroup - Three-dimensional nonlinear analysis program for pile groups under general loading

PileGroup is a finite-element based program which has been developed to calculate the deformations and loads of pile groups subject to general three-dimensional loadings such as axial and lateral forces and moments applied on the pile caps.

Main Benefits


Fast and efficient creation of analysis problem for pile group under general loadings


The user-friendly interface enables the user to efficiently create the analysis input file for pile groups under general loading with a logical workflow. It also provides the overview of ground profile and 3D displaying of deflection, shear force and bending moment distributions for individual piles within the group.

Interactive input of pile sections, pile head positions, pile lengths and pile batters for pile groups

The users can interactively input pile section, pile head positions, pile lengths and pile batters for pile group analysis problems. The whole process is simple, fast and also easy for the users to review and update if necessary.

Multiple sets of external loading can be applied at different positions on the pile cap


The external loadings (vertical loads Fy, horizontal loads Fx and Fz, rotational moment My, bending moments Mx and Mz) can be applied at any position on the pile cap and multiple sets of loadings can be specified by the users. The program will automatically calculate the equivalent loading at the origin in the analysis.

Well-designed graphical presentation dialog for all analysis results distributed along the length for individual piles within the group


Detailed analysis results for each pile with the group such as deflection, shear force, bending moment and mobilised soil reaction are plotted against the pile length and presented in the result output dialog graphically together with the soil layer geometry. The users can view, copy and print the results for the selected pile/piles.

Powerful 3D visualization of various pile group analysis results such as displacements, bending moments, shear forces and soil reactions


3D displaying of various pile group analysis results is available in PileGroup. It allows the users to zoom, rotate and move the displayed results smoothly in three-dimensional space with mouse or keyboard.

Deformed shape of pile group displayed in three-dimensional space

The users can view deformed shape of pile group once the analysis is successfully completed. Extensive displaying options such as model contour, pile and pile cap color, local and global axes, shape scaling factor and pile numbering are available in PileGroup for the users to personalize the 3D graphical presentation.

Load combinations for pile group analysis

The external loads applied at the pile cap are analyzed by the program through the load combinations defined by the users. Each load combination consists of multiple load cases on the pile cap and load factors for each load case.
