Mast Foundation

• Standard concrete and lightweight concrete are selectable
• Reinforced concrete with selectable concrete qualities and steel grades

• Square and rectangular as well as circular foundations
• As a differentiation criterion to shallow foundations and pile foundations, the ratio of the dimensions must be in the range 2/3 < D/A <= 4 (with A = width in the loading direction and D = foundation thickness) – this must be checked manually
• Selection of the reinforcement layer for the bending design

Position of foundation:

Global position coordinates and rotation angle

Column:

– Rectangular or round column
– Column dimensions

Soil:

• Freely selectable soil parameters
• Subgrade reaction moduli are automatically calculated from ϕ and D
• Several soil layers can be defined

Grundwater:

Definition of a groundwater horizon

Ground surface:

• Definition of ground level above sea level
• 4-sided different terrain definition possible
• Horizontal or continuously ascending or randomly broken slope course
• Optional ground load next to the foundation
• Different embedment depths per foundation side if necessary

• Self-weight optional
• Snow exceptional
• Any loads for biaxial effects of actions:
  • Vertical axial force Vz
  • Horizontal concentrated loads in the x- or y-direction
  • Concentrated moments about the x- or y-axis
• Free assignment of loads to types of actions according to EC 0 as well as to concurrency and alternative groups.
• Automatic combination of loads for the calculation of the decisive design load case for each verification.

• Definition of the permissible inclination
• Serviceability verification via the inclination by means of reaction moments

• Definition of the safety factor for the stability verifications
• Consideration of a minimum reinforcement
• Stability verification by means of earth pressures and reaction forces via design moments
• Bending design as per selected standard

Settings for bending design:

• Minimum eccentricity

Settings for reinforcement:

• Laying dimensions (sideways, bottom, top)
• Reinforcement layers (in x and y direction at the bottom and top)
• Diameter of the longitudinal reinforcement
• Diameter of the stirrup reinforcement
• Durability dialog

Settings for foundation engineering:

• Verification format “exact” or “user-defined”
• Stability verification in GEO limit state “active” or “off”
• Serviceability verification in SLS limit state (torsion verification) “active” or “off”

Earth pressure settings:

• Active earth pressure, increased active earth pressure or earth pressure at rest
• Minimum earth pressure and compaction earth pressure optional
• Wall friction angle active and passive optional
• Earth resistance with curved sliding surfaces if required
• Relocate option for earth resistance
• Mobilization factor for earth resistance optional
• Specified neutral axis optional
