GGU-UNDERPIN

GGU-Underpin GGU-UNDERPIN

Analysis and design of underpinning bodies (as a special case: design of footings) based on the Recommendations of the German Working Group for Excavations, EAB.


Capabilities:

  • Choice of analysis using either partial safety factors according to EC 7, DIN 1054:2010, Austrian Standard ÖNORM EN 1997-1 or global safety factors (DIN 1054 old) 
  • System input using absolute heights 
  • Analysis using active earth pressure, at-rest earth pressure and increased active earth pressure 
  • Active earth pressure coefficients according to DIN 4085, after Culmann or user-defined values 
  • Redistribution of the active earth pressure definable 
  • Consideration of earthquake according to EC 8 or EAU 1990, additionally consideration of a horizontal load from a rigid structure or from dead weight of the wall 
  • Passive earth pressure coefficients according to DIN 4085:2011, Streck, Caquot/Kerisel, Culmann or user-defined values 
  • Soil properties can be selected from an expandable database of common soils 
  • Berms on the active and the passive side 
  • Bounded and double-bounded surcharges on the active and passive side 
  • Loads with limited plan dimensions according to “Spundwand-Handbuch”, fig. 4.20, or DIN 4085:2017-08 
  • Consideration of displacement and action boundary conditions, anchors, struts, etc. 
  • Consideration of pre-tension and pre-deformation possible 
  • Horizontal water pressure approach: classical or with flow conduits according to the potential theory. With it: consideration of hydraulic gradients on the active and the passive side 
  • Verification of the bearing capacity resistance (including the 5° condition to DIN 4017) and of the sliding resistance 
  • Verification of highly eccentric loads and limitation of misalignment 
  • Settlement analysis according to DIN 4019 
  • Limiting depth analysis using p % of overburden stress, a multiple of footing width b' or a fixed value 
  • Verification of hydraulic heave safety and buoyancy safety  
  • Verification of the deep-seated stability with optimization of anchor lengths 
  • Unreinforced concrete design according to EC 2 / DIN 1054 or DIN 4093 
  • Anchor steel design 
  • Computation of the state variables and visualization of the moments of loaded struts 
  • Interface to the computer program GGU-STABILITY for the verification of the global stability 
  • Choice of visualization of earth pressure, water pressure, moments, shear force, normal force and bending line 
  • Graphical visualization summarizing various stages of construction 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
