Round column reinforcement (82)

Round column reinforcement (82) creates reinforcement for a concrete column that has a round cross section.

Objects created

Longitudinal main bars (6)
Stirrups
Column end reinforcement

Use for


Situation	Description
	Round concrete column with main bars bent outside the column. Continuous spiral stirrup.
	Round concrete column with straight main bars protruding from the column, or entirely inside the column. Separate stirrups. Top of the column is reinforced.

Limitations

Do not use for rectangular columns.

Selection order

Select the main part (column).
The component is created automatically when the part is selected.

Part identification key


	Part
1	Main bars
2	Stirrups
3	Column end reinforcement

Main bars tab

Use the Main bars tab to control the length of the vertical and horizontal extensions of the main bars at the top and bottom of the column, the thickness of the concrete cover over stirrups, and the cranking of the main bars.

Main bar properties


Option	Description
Number of bars	Number of main bars.
Rotation	Rotation of main bars.
Grade	Strength of the steel used in the reinforcing bars.
Size	Diameter of the main bars.
Bending radius	Bending radius of the main bars.
Class	Use Class to group reinforcement. For example, you can display reinforcement of different classes in different colors.
Name	Name for the main bars. Tekla Structures uses the name in drawings and reports.
Prefix	Prefix for the part position number.
Start number	Start number for the part position number.

Hooks at top / bottom


Option	Description
Type	Select the hook angle.
Length	Length of the hook.
Bending radius	Bending radius of the hook.

Cranking

You can create cranked reinforcing bars at the top and at the bottom of the column. Enter the vertical and sloped distance dimensions.

Enter the horizontal dimensions of top and bottom cranked bar as distance between center of bars or as outer distance of bars:

Stirrups tab

Use the Stirrups tab to control the thickness of the concrete cover over the stirrups at the top and bottom of the column, spacing and number of stirrups or laps in each stirrup group, stirrup types and stirrup shapes.

Stirrup dimensions

Thickness of the concrete cover over the stirrups at the top and the bottom of the column. The default cover thickness is 50 mm.

Group 1 is the top stirrup group, 5 is the bottom stirrup group. Group 3 is always created.
Spacing of stirrups in each stirrup group.
Number of stirrups in each stirrup group.
Select how the stirrups are distributed.
- Exact space, flexible at ends: Tekla Structures uses exactly the spacing value you specify, and evens out the stirrup distribution at the column ends.
- Target space: Tekla Structures creates the stirrups at even spacings and tries to use the spacing value you specify.

Stirrup types


Option	Description
	Separate stirrups
	Single, continuous spiral stirrup
	Separate spiral stirrups
	Single, continuous stirrup

Stirrup shape

Select the shape of the stirrup from the list.

Stirrup overlap

Select the angle or the length of stirrup overlap. The option is not active if you have created spiral stirrups.

The overlapping angle can be of maximum 180 degrees.

The overlapping length can be in millimeters or inches.

Hooks at start / Hooks at end

Define the hook settings for the stirrups. You can define the type, length, and bending radius separately for the hooks at the start and the end.

Stirrup attributes tab

Use the Stirrup attributes tab to control the grade, size, class, name, and numbering properties of the stirrups.

Top tab

Use the Top tab to control the thickness of the concrete cover of the top reinforcement, the number of top bars, and their spacing and rotation.

Column top reinforcement

Define the concrete cover thickness.
Define the length of the ultimate leg.

Column top reinforcement rotation

Select how to rotate the reinforcement at the top of columns.

Advanced (main bars) tab

Use the Advanced (main bars) tab to control the main bar extensions separately for each bar.

Extensions


Option	Description
	In Bar index, enter the bar number for which to define the extension. Define the size, the distance from the column edge and the length of each extension. Select whether the main bars are tapered or moved according to the upper surface, if the top of the column is skewed.
	Select whether to cut bars by the cut in the column.

Rebar grouping

Select to create bars as a rebar group or as single bars from the Creation method list.

Rebar assembly tab

Use the Rebar assembly tab to add the created reinforcement as a rebar assembly to the cast units.

Create as rebar assembly

You can add the created reinforcement as a rebar assembly to the cast units with a predefined assembly type, name, prefix, and start number.


Option	Description
Create as rebar assembly	Select Yes to create all reinforcement as one rebar assembly, and to include it to the cast unit of the input part.
