GGU-Retain

The following retaining walls can be designed with this software:

• Sheet pile wall
• Soldier pile wall
• In-situ concrete wall (diaphragm wall,
  bored pile wall, contiguous wall)
• CMG (cut-mix-grout) wall

Capabilities:

• 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)
• Sheet pile wall analysis using EC 3-5
• Steel analysis using EC 3
• Berms on the active and the passive sides
• Bounded and double-bounded surcharges on active and passive sides
• 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
• Seismic effects via altered earth pressure coefficients to EC 8 or EAU 1992
• Consideration of hydraulic gradient on the active and the passive sides
• Verification of hydraulic heave safety,
  buoyancy safety, base heave safety,
  heave of anchor soil , pull-out resistance
• Deep-seated stability with optimisation of anchor lengths
• Input of displacement and action boundary conditions, anchor and strut locations, pre-deformations and much more

• Automatic search for the earth pressure redistri utions proposed by the EAB + EAU
• Continuous elastic support in the toe area with any profile
• Expandable database using standard
  profiles for oldier piles and sheet piles
• Anchor steel design
• Reinforced concrete design and crack width verification to DIN 1045-1 for circular and rectangular cross-sections
• Buckling analysis to DIN EN 1993-1-1 using 2nd order theory
• Design of infill for soldier pile walls
• Choice of visualisation of earth pressure, water pressure, moments, shear force, normal force and bending line
• Graphical visualisation summarising various advancing and retreating stages
• Retaining wall as legend
• Interface to the GGU-STABILITY program (slope failure analyses)
• User-defined design of output sheet
• Print or copy screen sections, e.g. for transfer to a word processor
• Integrated Mini-CAD system for additional annotation of graphics
