GEO5 version 13

New programs

MSE Wall – Mechanically Stabilized Earth Walls design

General improvements

* Modelling of water as a result of ground water flow analyses (FEM)
* Seismic design according to EN 1998, dynamic effect of water
* New method of determination of pull-out bearing capacity of nails
* Consolidation analysis of non-homogeneous layered soil
* New way of passing soil type and its parameters among programs
* Improved output reporting system:

• RTF export
• Compatibility with Office 2010
• Smart word wrap
• New explorer window
• Unicode (national symbols support)

Spread Footing
* Simplifications of calculations according to EN 1997, Design approach no. 1

Piles
* Simplifications of calculations according to EN 1997, Design approach no. 1
* implementation of settlement limit for nonlinear load curve

Terrain
* new faster internal solver
* DXF import in construction stages

All wall programs

* possibility to choose vertical earth wedge
* influence of earthquake on soil wedge
* modification of earthquake influence on wall under water
* dynamic water pressure in front of the structure
* switch of geo-reinforcement to resisting forces

Sheeting
* dynamic water pressure in front of the structure

Cantilever Wall
* earthquake analysis for pressure at rest according to EN 1998

Pile CPT
* partial factors revised according to EN 1997-2

Sheeting Check
* reduction of subgrade reaction modulus below ditch bottom
* more detailed output of internal stability

Slope Stability
* increase of normal stress due to anchors (Bishop, Fellenius)

Corrections

* Spread footing – load bearing capacity on rock subgrade according to EN – input of ɣQu partial factor
* Spread footing – limitation of max. Qu value by 10Mpa resp. 5MPa
* Spread footing – correction of tensioned spread footing dimensioning, floating point overflow
* All walls – incorrect print messages of earthquake intermediate results eliminated
* Spread footing – calculation modification of punching shear for unusual shapes of critical plane
* All walls – correction of incorrect numbering of layers for intermediate results printing
* Spread footing – elimination of unselected forces for eccentricity calculation of strip footing
* Pressures – change of calculation of influence of strip surcharge (pressure at rest)
* Nail – correction of nail stiffness export to Slope stability
* Slope stability – correction of calculation according to Sarma for vertical anchor
* Gabion design – correction of calculation of block weight under water
* Pile – printing of alpha partial factor for Tomlinson method corrected
* Slope stability – influence of inclined water level for Rapid draw down calculation added
