Add Pile or Forepole Pattern

Piles/Forepoles can be added as individual (single) piles or pile patterns to selected faces of external volume pieces.

To add Piles/Forepoles as a pile pattern to a selected face:

  1. Select the Support Support workflow tab workflow tab.
  2. Select Faces Selection Faces Selection tab as the Selection Mode.
  3. Select the face on which to add the pile pattern.
  4. Select Add Piles or Forepoles Add Piles or Forepoles icon from the toolbar or the Piles & Forepoles Piles & Forepoles icon sub-menu of the Support menu.
  5. TIP: with the face selected, you can also right-click on the viewing screen and select Add Piles or Forepoles from the Support sub-menu.

  6. You will see the Add Piles/Forepoles dialog. In this dialog:
    • select the Pile/Forepole Property type.
    • select the pile/forepole Orientation (e.g. Normal, Trend & Plunge, or Vector).
    • select the pile/forepole Direction, by specifying the Axis and Imin Direction.
    • enter the Length of the pile/forepole to be used in the pile pattern.
    • in a multi-stage mode, the Staging options allow you to specify the stage at which the piles(s)/forepole(s) will be installed and the stage at which the pile(s)/forepole(s) will be removed. In addition, it can be selected to automatically remove pile(s)/forepole(s) in excavated material using the available option.
    • select Application = Pile Pattern.

See below for details about the property, orientation, direction, length, staging, application, and pile pattern.

  1. Select the Set Primary Path Set path button button. In the view window, use left click on the mouse to select the beginning of the primary path. Use left click on the mouse to select the end of the primary path. These start and end points of the primary path will determine the range in which piles of the pile pattern will be added in this primary direction.
  2. Select the Set Secondary Path Set Path button button. In the view window, use left click on the mouse to select the beginning of the secondary path. Use left click on the mouse to select the end of the secondary path. These start and end points of the secondary path will determine the range in which piles of the pile pattern will be added in this secondary direction.
  3. Enter the Primary Spacing, Secondary Spacing, Primary Offset, and Secondary Offset for the pile pattern.
  4. When all of the parameters for the pile pattern have been entered, select the Preview Pattern Preview Pattern button button. Each pile of the pattern is represented as a square on the surface of the selected face.
  5. When the pattern appears as desired, select the Add Add button button.
  6. When all piles/forepoles have been added to the selected face, select Done to complete and close the dialog.

Pile/Forepole Property

You can select a Pile/Forepole Property type in the Add Piles/Forepoles dialog. If you wish to edit the pile/forepole properties you can use the Edit Pile Property Edit Pile Property button shortcut button beside the Pile property type list.

Pile/Forepole Orientation

The Orientation may be specified using one of the following options:

  • Normal - piles/forepoles are applied normal to the boundaries
  • Trend/Plunge - specify a trend and plunge
  • Vector (x,y,z) - specify a vector from the x, y, and z-directions

Flip Orientation

NOTE: after adding a pile/forepole, the orientation may sometimes be opposite from the intended direction (i.e. 180 degrees off). If this occurs, you can select the pile and use the Properties pane option to "flip" (i.e. reverse) the load orientation by 180 degrees.

Pile/Forepole Direction

Remember that in RS3 a pile is simulated as a Beam, with additional properties to account for the pile/soil interface behaviour. In order to define how beams/piles are installed on a boundary with respect to the beam cross-section, you must choose a beam Axis and Imin Direction.

AXIS

You may choose either the Imin Axis or the Imax Axis of the beam cross-section to represent the beam cross-sectional axis.

NOTE: the actual values of Imin and Imax are entered in the Define Beam Properties dialog.

IMIN / IMAX DIRECTION

You must then choose a direction for the chosen beam axis. The following options are available:

  • Normal
  • Trend & Plunge
  • Vector

Pile/Forepole Length

The length of all piles/forepoles as measured along the axis of the pile/forepole.

Staging

If your model is staged, you can specify the installation and removal stage of piles/forepoles.

  • Install at stage - by default the installation stage will be set to the stage that you are currently viewing (i.e. the currently selected stage tab). You can enter a different stage if necessary.
  • Remove at stage - by default the removal stage will be set to never. You can enter the stage at which the piles/forepoles are to be removed (uninstalled), if applicable.

AUTO-REMOVE IN EXCAVATED MATERIAL

The piles/forepoles can be automatically removed in excavated materials if the Auto-remove in excavated material checkbox is selected.

Pile/Forepole Application and Pile Pattern

In RS3, Piles/Forepoles can be added as Single Pile or Pile Pattern. The Pile Pattern option allows the user to define a region (on the selected face) on which a pattern of piles will be added. This region is defined by the Primary Path and the Secondary Path. The start points selected for both the primary and secondary paths should be the same.

PRIMARY PATH

The Primary Path is the primary direction of the pile pattern.

SECONDARY PATH

The Secondary Path is the secondary direction of the pile pattern.

PRIMARY SPACING

The Primary Spacing is the spacing between each pile of the pattern in the primary direction.

SECONDARY SPACING

The Secondary Spacing is the spacing between each pile of the pattern in the secondary direction.

PRIMARY OFFSET

The Primary Offset allows you to define a starting location for the pattern in the primary direction, as measured from the starting point of the Primary Path.

SECONDARY OFFSET

The Secondary Offset allows you to define a starting location for the pattern in the secondary direction, as measured from the starting point of the Secondary Path.

Preview Pattern

The Preview Pattern Preview Pattern button button displays the pattern of the currently-configured pile pattern on selected surface of the model.
