Footing Geometry page

Used to input geometry parameters used in design or checking.

SettingDescription
Design Type

There are two types of design one is calculate dimension another is set dimension:

  • Calculate - The footing size will be checked and resized to the smallest size which meets all specified loads; ranging between the minimum and maximum dimensions provided (inclusive). Calculate dimension is set by default.
  • Set Dimension - then the minimum dimensions will constitute the only footing size checked.
Minimum Length

Specify the minimum length (direction parallel to the X axis) to be used for the footing design, along with unit.

Minimum Width

Specify the minimum width (direction parallel to the Y axis) to be used for the footing, along with unit.

Minimum Thickness

Specify the minimum thickness (direction parallel to the Z axis; or out-of plan dimension) to be used for the footing, along with unit.

Maximum Length

(Calculate only) Specify the maximum length (direction parallel to the X axis) to be used for the footing design, along with unit.

Maximum Width

(Calculate only) Specify the maximum width (direction parallel to the Y axis) to be used for the footing, along with unit.

Maximum Thickness

(Calculate only) Specify the maximum thickness (direction parallel to the Z axis; or out-of plan dimension) to be used for the footing, along with unit.

Plan Dimension Inc.

(Calculate only) Specify the length and width increments to be used when performing footing design, along with unit. This allows you control over how to step footing sizes in design results.

Thickness Increment

(Calculate only) Specify the thickness increments to be used when performing footing design, along with unit.

Offset X / Z Direction

If the loads do not pass through the CG of the footing, specify the offset dimension in the X and Z directions (parallel to length and width, respectively), along with unit.

Length Width Ratio

(Calculate only) Specify a plan aspect ratio to control the relative length and width of the footing design.

For example, a value of one results in a square footing where as a value of two results in a footing twice as long along the X axis as the Z axis width.
