Analysis and design of underpinning bodies


  • System input using absolute heights
  • Choice of analysis using either partial safety factors to DIN 1054:2005 or EC 7 or global safety factor (DIN 1054 old)
  • Consideration of active and passive berms
  • Consideration of active and passive bounded and double-bounded surcharges
  • Consideration of displacement and action boundary conditions, anchors and struts etc.
  • Analysis using active earth pressure, at-rest ea th pressure and increased active earth pressure
  • Active earth pressure coefficients to DIN 4085 or user-defined values
  • Passive earth pressure coefficients to DIN 4085:2011, Streck, Caquot/Kerisel or user-defined values
  • Consideration of hydraulic gradients on the active and the passive side
  • Analysis of bearing capacity safety to DIN 4017 with "5% condition" test
  • Settlement analysis to DIN 4019
  • Limiting depth analysis using x % of overburden stress, a multiple of the footing width or as a fixed value
  • Verification of sliding safety, hydraulic heave and buoyancy safety
  • EQU analysis
  • Unreinforced concrete verification
  • Anchor steel design
  • Verification of deep-seated stability with optimisation of anchor lengths
  • Consideration of prestressing of anchors and struts possible
  • State variables can be selected for struts under load
  • Seismic effects via additional horizontal loads and/or altered earth pressure coefficients to EC 8 or EAU 1992
  • Automatic search for earth pressure redistributions proposed by EAB
  • Choice of result presentation for earth pressure, water pressure, moment, shear force, normal force and bending line
  • 50 additional earth pressure distributions, 20 area loads at any depth
  • Graphical visualisation summarising various advancing and retreating stages
  • Interface to the GGU-STABILITY (slope stability analysis)
  • Adopted standard, program name and version can be included in the General legend
  • Freely definable positioning and sizing of graphical elements and legends
  • Print or copy screen sections, e.g. for transfer to a word processor
  • Integrated Mini-CAD system for additional annotation of graphics
