Pad Foundation

• Reinforced concrete with selectable concrete qualities and steel grades
• Different materials for the foundation and the column

• Square and rectangular foundations
• Optionally with eccentric column
• With interior base (block foundation)
• Toothed pocket surface (design in accordance with Leonhardt or Schlaich/Schäfer)

Soil:

• Any number of horizontal layers
• Freely selectable soil parameters
• Permissible base pressure resistance based on empirical values of DIN 1054

Ground surface:

• Horizontal or continuously ascending
• Any number of polygonal ground-surface sections

Groundwater:

• Stagnant groundwater can optionally be taken into account at any height level.

• Any column loads for biaxial loading, if applicable
  • Vertical concentrated load V
  • Horizontal concentrated load in the x- or y-direction (optionally applying to the top edge of the pocket or the foundation)
  • Concentrated moments about the x-axis and the y-axis
• Any additional loads applying to the foundation as concentrated loads, line loads or area loads.
• Free assignment of loads to types of actions according to EC 0 as well as to concurrency and alternative groups.
• General separation of the definition of design loads and of characteristic loads with automatic load case combination

• Punching shear analysis with/without punching shear reinforcement
• Punching shear in the erecting state
• Bending design
• Shear force design
• Pocket design with strut-and-tie models
• Durability verification via exposure classes
• Consideration of different minimum reinforcement quantities
• The reinforcement dialog allows the definition of any reinforcement and arrangement

Pocket design

• On the equivalent beam (toothed)
• In accordance with Schlaich/ Schäfer (“Beispiele zur Bemessung nach Eurocode 2”, volume 1)

• Simplified verification with base pressure resistances (either user-defined or based on tables of DIN 1054)
• Optional verifications using the accurate calculation method:
  • Overturning
  • Sliding
  • Ground failure
• Optional settlement verification
• Serviceability via the verification of the gaping joint and torsion

• PDF
• Word
• Printer

• Various output profiles available for selection (brief, detailed, user-defined)
• Selectable graphic scales and font sizes
• Detailed output of individual load cases
• Overview of the decisive load case combinations and their assignment to the design situation (persistent, transient, accidental and earthquake)
• Reinforcement sections can optionally be output in the form of a reinforcement plan

• Decisive base pressure distribution for the individual design calculations
• Detailed results in graphical and tabular form of the bending design in the x- and y-direction at the top and bottom of the foundation
• Graphical representation of the reinforcement distribution and, if applicable, staggered reinforcement quantities
• Detailed graphical and tabular representation of the results of the punching shear design
• Detailed output of the pocket design, if applicable
• Details on calculated lapping and anchorage lengths

• Tabular and graphical output of the selected decisive actions and base pressures for each selected geotechnical verification

With the additional option FDPro, the foundation programs FD+, FDB+, FDS+ and GBR+ can be extended to include:

• an earth pressure approach
• an inclined foundation base
• a seismic ground failure verification
• a ground failure – punching shear verification
• a bearing capacity calculation of the foundation soil with a table of design values of the base pressure resistance.
• a graphical output of the internal forces along the main axes

Note on the free 30-day demo
The additional option FDPro can also be tested for 30 days without a license. As soon as you call up a function from FDPro, you will be asked whether the function should start as a demo.
