Program DynaPile was developed to compute the dynamic stiffness of single piles or pile groups. The piles can be either floating piles or end-bearing piles. Vertical, horizontal and rocking dynamic stiffnesses will be generated by the program. The program will also generate the group reduction factors for pile groups under small excitation conditions. The method of computation is based on the consistent boundary-matrix method proposed by Blaney, Kausel and Roesset (1976).
Pile foundations were analyzed for some time neglecting interaction effects betwwen the piles through the soil and enforcing only compatibility of displacements at their heads under the assumption of a rigid mat. The dynamic model, which takes into account the whole soil medium in the analysis, can conveniently provide information about group-reduction factors of pile foundations if the soil properties are adjusted to account for the effective level of strains.
Input parameters consist of the structural and dynamic properties of the pile, geometric configuration of the pile groups, soil properties, definition of excitation forces (in frequencies), and definition of superstructures masses.

DynaMat uses a three dimensional hybrid method to estimate the equivalent dynamic stiffness and damping of machine foundations.
DYNAN can be used for the dynamic analysis under transient and random loading in the time domain.
GROUP has been well accepted as an useful design tool for analyzing the behavior of piles in a group subjected to both axial and lateral loadings.
PileGroup calculates 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.
spMats is highly efficient and widely used for analysis, design and investigation of commercial building foundations and industrial mats and slabs on grade.
