GGU-UNDERPIN

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)
• Consideration of active and passive berms
• Consideration of active and passive bounded and double-bounded surcharges
• Consideration of displacement and action boundary conditions, anchors and struts etc.
• 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
• Consideration of hydraulic gradients on the active and the passive side
• Analysis of bearing capacity safety to DIN 4017 with "5% condition" test
• Settlement analysis to DIN 4019
• Limiting depth analysis using x % of overburden stress, a multiple of the footing width or as a fixed value
• Verification of sliding safety, hydraulic heave and buoyancy safety
• EQU analysis
• Unreinforced concrete verification
• Anchor steel design
• Verification of deep-seated stability with optimisation of anchor lengths
• Consideration of prestressing of anchors and struts possible
• State variables can be selected for struts under load
• Seismic effects via additional horizontal loads and/or altered earth pressure coefficients to EC 8 or EAU 1992
• Automatic search for earth pressure redistributions proposed by EAB
• Choice of result presentation for earth pressure, water pressure, moment, shear force, normal force and bending line
• 50 additional earth pressure distributions, 20 area loads at any depth
• Graphical visualisation summarising various advancing and retreating stages
• Interface to the GGU-STABILITY (slope stability analysis)
• 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
