  • Analysis using Blum's method or p-y method (modulus of subgrade reaction method with non-linear spring characteristics)
  • Analysis using partial safety factors to EC 7
  • Steel analysis using EC 3
  • Required working capacity determination using different equations
  • Expandable database for sections
  • Simulation of steel sections corrosion
  • Analysis of a selected load case or comparative analysis of several load cases in a single computation
  • Analysis with a selected section or with optimum section determination
  • Analysis using different sections possible for a dolphin
  • Graphic supported section length optimisation in analysis using different sections
  • Buckling analysis with fy,k reduction or according to DIN EN 1993-1-6
  • Analysis of sum V
  • System input using absolute heights
  • Soil properties can be selected from an expandable database of common soils
  • Definition of up to 10 load cases possible
  • Passive earth pressure calculation to DIN 4085:2017 or DIN 4085:2017 planar slip surfaces
  • Three-dimensional passive earth pressure to DIN 4085:2017
  • Consideration of seismic effects via altered earth pressure coefficients to EC 8
  • Result presentation for earth pressure, moment, shear force, normal force and displacement in the system graphics
  • Analysis results can also be presented in different legends and as output table
  • Visualisation of p = f(y) function curves in a legend
  • Visualisation of the used section as sketch in a legend
  • Adopted standard, program name and version can be included in the
  • General legend
  • User-designed output sheet
  • Print or copy screen sections, e.g. for transfer to a word processor
  • Integrated Mini-CAD system for additional annotation of graphics

GGU-DOLPHIN analysis and design of dolphin piles (62min)

Welcome to the introduction to the programm GGU-DOLPHIN.

GGU-DOLPHIN allows the analysis and design of dolphin piles which are loaded horizontally in most cases. After a short introduction you will see the menues of the hole program and some examples. 

We have made this short training course available to you free of charge.
