GGU-Retain GGU-RETAIN

Analysis of retaining walls based on the Recommendations of the german Working Group for Excavations and for Waterfront Structures (EAB + EAU).


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
  • Combined sheet pile 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)
  • 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
  • Simulation of sheet pile sections corrosion
  • 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

 


Current updates & changes

  • 10.22 (11.03.2020)
    • Vertical capacity: The end resistance qb,k can now also be averaged directly using the corresponding table values without averaging qc or cu,k. This is advantageous if there are cohesionless and cohesive soils in the wall base zone of influence.

     

  • 10.21 (28.02.2020)
    • Reduction of cohesion (R 14) can be turned off for analysis of Sum H.

     

  • 10.20 (17.02.2020)
    • Construction phases now with envelope for reinforcement.

     

  • 10.19 (06.02.2020)
    • Bugfix: Vertical capacity for bedded systems and Method 1
    • 2019 EAU annual report implemented.
  • 10.18 (29.01.2020)
    • Reduction of cohesion compliant with R 14 now also for analysis of Sum H, heave FOS, export to GGU Stability and length surcharge
    • Optimisation of the analysis of vertical capacity compliant with procedure 2
