FRILO Isolated Foundation FD+

Material

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

Structural system

• Square and rectangular foundations
• Optionally with eccentric column
• Optionally with interior and exterior base (pocket)
• Smooth or 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

Loads

• 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.

Reinforced concrete design (internal stability)

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

Geotechnical verifications (external stability)

• 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
