Pile layout (Parametric) page

Used to specify pile arrangement for a pile cap by entering rectangular and circular pile arrangements.

Note: If circular arrangement is chosen, the program will design that pile cap as Octagonal Pile Cap.
SettingDescription
Pile Arrangement for Support

Used to select a support from the current job for which you would like to input pile arrangement.

Spacing selection

Select to use either a Row Spacing or Column spacing for Rectangular layout.

Pile Data

Used to input the forces that a pile is meant to bear.

Unit

The Unit drop-down list box allows you to select the force unit used for Pile Capacity and length unit used for spacing, diameter, edge distance etc.

Lateral

Specify the lateral capacity of a pile.

Vertical

Specify the vertical capacity of a pile.

Uplift

Specify the uplifting capacity of a pile.

Dia

Diameter of a pile.

Edge

The Edge Distance field allows you to specify the distance between the edges of a pile.

Arrangement Type

Pile arrangement can be either rectangular or circular. Pile cap having circular arrangement will be design as octagonal pile cap.

Rectangular arrangement needs following inputs,

  • Number of Rows
  • Number of Columns
  • Row Spacing
  • Column Spacing

By default program will create symmetric pile arrangement from the above input but user can change the default setup by editing the table below. Both row and column grid lines can be adjusted by selecting appropriate radio button.

Circular arrangement needs following inputs as shown below.

  • Number of Piles – Total number of piles, excluding the center pile (if option is selected).
  • Number of Layers – Number of concentric circles in the circular arrangement.
  • Pile Spacing – Minimum spacing between piles
  • Use Center Pile – Select this option to add a pile at center of pile arrangement.

By default, program will try to assign equal number of piles for all concentric circular layers. The arrangement can be edited using the table below.

Create Pile Arrangement

Creates the pile layout and opens a dialog box to display the pile coordinates table and a figure.

Note: Pile coordinates in this table are editable.

Delete Row - Click to delete the current row from the pile coordinate table and figure.

Select Current Arrangement

Once a satisfactory pile layout has been found, click the Select Current Arrangement button to select and apply that layout.

The program will check the pile reaction against pile capacity to make sure pile reactions do not exceed pile capacity values.

Show Pile Reactions

The Show Pile Reactions button opens a table displaying the reaction on each pile. The figure below shows the pile reaction table.
