Pile cap reinforcement (76)

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

Bars created


Situation	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

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


Shape	Description
	Rectangular
	Skewed on two sides
	Skewed on one side
	Rectangular with cut corners

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.

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


Option	Description
Grade	Strength of the steel used in the reinforcing bar. This field cooperates with the Size field.
Size	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.
Creation method	By spacing A accompanying field becomes active. The entered value is the fixed spacing for the rebars. The number of rebars is calculated automatically.

Define the pile cap reinforcement using the following properties:


Field	Description
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.

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:

To create lacer bars for a footing:


Property	Description
	Quantity, spacing, and location of lacer bar groups. Tekla Structures only uses information from some of the fields, in this order of priority: Number of bars and Spacing Number of bars, Start, and End Spacing, Start, and End
Type	The number and location of laps. The options are:
Orientation	The options are Default, Front, and Back.
p1...p4 L1...L4	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.

Use the Attributes tab to define numbering properties of bars.


Option	Description
Prefix	Prefix for the bar position number.
Start number	Start number for the bar position number.
Name	Tekla Structures uses the name in drawings and reports.
Class	Use Class to group reinforcement. For example, you can display reinforcement of different classes in different colors.
