GGU-Underpin GGU-UNDERPIN

Analysis and design of underpinning bodies

CapabilitiesUpdates & Changes

Capabilities:

  • Choice of analysis using either partial safety factors to DIN 1054:2010, EC 7, Austrian Standard ÖNORM EN 1997-1 or global safety factors (DIN 1054 old)
  • Bearing capacity safety and settlement analysis to DIN 4017 and DIN 4019
  • Verification of sliding safety, hydraulic heave and buoyancy safety
  • EQU analysis
  • Inner stability analysis to DIN 4093
  • Unreinforced concrete analysis
  • System input using absolute heights
  • Soil properties can be selected from an expandable database of common soils
  • Consideration of active and passive berms • 
  • Analysis using active earth pressure, at-rest earth pressure or increased active earth pr. • 
  • Active earth pressure coeff. to DIN 4085
  • Passive earth pressure coefficients to DIN 4085:2017, Streck, Caquot/Kerisel
  • Consideration of hydraulic gradients on the active and the passive side
  • Seismic effects via additional horizontal loads and/or altered earth pressure coefficients to EC 8
  • Consideration of displacement and action boundary conditions, anchors and struts etc. •
  • Consideration of active and passive bounded and double-bounded surcharges •
  • 20 area loads at any depth
  • Consideration of prestressing of anchors and struts possible
  • Verification of deep-seated stability with optimisation of anchor lengths
  • Anchor steel design
  • State variables can be selected for struts under load "5°" condition check to DIN 4017
  • Limiting depth analysis using different methods
  • Automatic search for earth pressure redistributions proposed by EAB
  • 50 additional earth pressure distributions • Interface to the GGU-STABILITY (slope stability analysis)
  • Choice of result presentation for earth pressure, water pressure, moment, shear force, normal force and bending line
  • Graphical visualisation summarising various advancing and retreating stages 
  • 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
