Geotechnics

SOFiSTiK offers many programs to accomplish general geotechnics such as soil and foundation engineering tasks:

 

TALPA

TALPA allows the linear and non-linear deformation and stress determination of any formed plain structure, which are loaded in their plain as well as of axial symmetrical 3D structures according to the Finite Element Method (i.e. embankments, tunnel disks, building pits, dam walls etc). The system input can be done using WinTUBECADINPSOFiPLUS or via the program especially suited for excavations WallsFEM.

 

HASE - Soil Structure Interaction  

The program HASE is used for the analysis of vertical deformations in semi-infinite solids according to the stiffness coefficient method. The settlement of large complex constructions can be analysed, as well as their influence on neighbouring structures. A 2/3D Ground-Soil interaction can be conducted via the combination with the modules SEPP, ASE and STAR. The system input is done via CADINP, SOFiPLUS or the FIDES input program GroundSlab, which is especially suited for 2D-systems.

 

 

PFAHL - Analysis of pile foundations

The program PFAHL is used for the analysis of individual piles and general pile structures. The pile element is an elastically bedded beam, for which a variable bedding profile can be defined in circumferential- and longitudinal direction. The superstructure is defined as a rigid system via coupling or as an elastic system with existing stiffness' via beams or finite elements.  In addition an analysis according to 2nd order theory is also possible. Therefore the buckling check can be conducted in an easy, concise and graphical way. The input is done using CADINP, SOFiPLUS or the FIDES program PilePRO, which is especially suited for pile structures.

 

 

HYDRA - Analysis of potential problems

A large number of physical problems can be described by potential problems and can thus be classified as Laplace's (DH=0) or Poisson's (DH=q) differential equations. They consist of e.g. magnetic field problems, heat conduction problems and groundwater flow. HYDRA is specialized on the calculation of the last two problems, although it can also handle other problems of this type. The system input is mainly done using CADINP or WinTUBE and supplementary with SOFiPLUS.
