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
