Analysis of elastically supported slabs based on the modulus of subgrade reaction and constrained modulus methods using the finite-element method.


  • Subgrade modulus profile can be varied as required
  • Constrained modulus distribution can be defined via stratigraphic profiles and interpolation mesh
  • FEM mesh coordinates can be imported from a table via the Windows clipboard
  • Soil properties can be selected from an expandable database of common soils
  • Export constrained modulus profiles and mesh to GGU-SETTLE
  • Limiting depth analysis to DIN 4019 for constrained modulus method
  • Consideration of vibrodisplacement compaction after Priebe
  • Consideration of kappa correction coefficients (DIN 4019)
  • Automatic computation of Young's modulus from Es and nu
  • Visualisation of internal forces: moment, shear force, displacement (including determination of torsional stiffness for multi-layered systems) and pressure
  • Any type of slab boundary including with holes
  • Linearly variable subgrade within an element
  • Powerful mesh generator (for generating circular, annular and elliptical slabs)
  • Beam elements for modelling foundation beams, for example
  • Single springs, perpendicular to slab, e.g. for modelling piles• Slab reinforcement to EC 2
  • Numerous options for visualising the evaluation results, e.g. as contour lines
  • 3D graphics or in section
  • Analysis and visualisation of settlement depressions
  • Autosave function
  • User-designed output sheet
  • Print or copy screen sections, e.g. for transfer to a word processor
  • Integrated Mini-CAD system for additional annotation of graphics
