Pile cap reinforcement (76)

Pile cap reinforcement (76) creates reinforcement for a concrete pile cap.

Bars created

  • Bars in two directions for the top and bottom surfaces of the pile cap

  • Lacer bars

Use for


More information

Bottom bars concentrated over the piles, top bars under the column. Two lacer bars.

Bars evenly distributed on the bottom and top surfaces. No lacer bars.

Rectangular footings with or without cut corners, footings that are skewed on one or both sides

Pad footing and pile cap shapes

Bars on the top, bottom, or both surfaces of the footing

Straight or bent bar ends

Pad footing and pile cap shapes

Use the Pile cap reinforcement (76) to create reinforcement for the following shapes of foundations:




Skewed on two sides

Skewed on one side

Rectangular with cut corners

Before you start

  • Create the concrete pile cap.

  • Calculate the required area of reinforcement.

Selection order

  1. Select the concrete pile cap.

  2. Select the piles and/or columns.

  3. Click the middle mouse button to finish.

Picture tab

Use the Picture tab to define the concrete cover thickness and primary bar direction.

Enter the concrete cover thicknesses:

Select the primary bar direction to either Parallel with longer dimension or Parallel with shorter dimension.

Primary/Secondary top bars and Primary/Secondary bottom bars tabs

Use the Primary/Secondary top bars and Primary/Secondary bottom bars tabs to define the bar properties.

Bar properties




Strength of the steel used in the reinforcing bar. This field cooperates with the Size field.


Diameter of the reinforcing bar. Pressing the ... button right of the field will open the Select rebar dialog box.

In the dialog box you can select the grade and the accompanying diameter.

Note: Selecting a size will override the value in the Grade field.

End conditions left/right

Defines the shape of the rebar end.

Default value is Straight.

Bend lengths left/right

Defines the length of the left/right end-extension.

Creation method

Number of bars

A fixed number of bars is created. The spacing between the bars is automatically calculated.

By spacing

A accompanying field becomes active. The entered value is the fixed spacing for the rebars. The number of rebars is calculated automatically.

Pile caps

Define the pile cap reinforcement using the following properties:



To suit pile/column

Select Yes to concentrate main bars over piles and under columns.

% of pile/column width

The area where the bars are concentrated, as a percentage of the width of the pile or column.

For example, if the pile diameter or width is 500 mm, enter 120 in the % of pile width field to concentrate bars in a 600 mm-wide area over the pile.

Bar portioning (%)

The proportion of bars concentrated over a pile or under a column.

Bar portioning (number of bars)

The number of bars concentrated over a pile or under a column.

Lacer bars tab

Use the Lacer bars tab to create and define lacer bars.

Lacer bars are reinforcing bars that loop around the sides of a concrete footing.

You can create up to six different groups of lacer bars in a footing. Each group can contain different values for:

  • Grade

  • Bar size

  • Number of bars

  • Spacing

  • Shape

  • Dimensions

To create lacer bars for a footing:

  1. In the Lacer bar option list box, select Yes to create lacer bars.

  2. Enter properties for each lacer bar group:



Quantity, spacing, and location of lacer bar groups.

Tekla Structures only uses information from some of the fields, in this order of priority:

  1. Number of bars and Spacing

  2. Number of bars, Start, and End

  3. Spacing, Start, and End


The number and location of laps. The options are:


The options are Default, Front, and Back.



The exact locations and lengths of lacer bar laps. Locations are measured from the corner of the bar to the midpoints of laps.

The location of the topmost lacer bar, measured from the end of main bars.

Entering a value here overrides the location defined in the End field.

Attributes tab

Use the Attributes tab to define numbering properties of bars.




Prefix for the bar position number.

Start number

Start number for the bar position number.


Tekla Structures uses the name in drawings and reports.


Use Class to group reinforcement.

For example, you can display reinforcement of different classes in different colors.
