Example: Add a corbel connection using Corbel connection (14)

In this example, you will add a corbel connection between a column and a beam.

Click the Applications & components button in the side pane to open the Applications & components catalog.
Enter corbel in the search box.
Select Corbel connection (14).
Select the main part (column).
Select the secondary part (beam).

Tekla Structures automatically adds the corbel connection between the column and the beam when you select the beam.

Picture tab

Use the Picture tab to control the corbel shape and dimensions, beam end shape and dimensions, and corbel side chamfers in Corbel connection (14).

When beam sloped, adjust

If the beam in the connection is sloped, define whether the beam or the corbel is cut.

When the beam end is cut, the corbel top stays horizontal. When the corbel is cut, the corbel top has the same slope as the beam.

Corbel dimensions and shape


	Description
1	Gap between the column and the beam.
2	Gap between the corbel and the beam.
3	Vertical corbel dimension.
4	Beveled corbel dimension.
5	Corbel width.


Option	Description
	Default Beveled corbel AutoDefaults can change this option.
	Beveled corbel
	Square corbel
	Rounded corbel

Corbel position


	Description
1	Horizontal corbel offset.
2	Height of the beam cut.
3	Gap between the corbel and extended beam.

Beam end shape

You can fit the beam end to the column, or you can create a straight beam end.


Option	Description	Example
	Default Straight beam end AutoDefaults can change this option.
	Straight beam end
	Beam end is fit to the column based on the dimensions you define. Beam can extend symmetrically on both sides of the column, or with different dimensions.

Corbel thickness

Define the distances from column edges to set the corbel thickness.

Corbel side chamfers

Define whether the corbel sides are chamfered. By default, no chamfers are created.

Parts tab

Use the Parts tab to control the corbel part properties and dimensions in Corbel connection (14).

Using custom components as fastening plates

You can use custom components as fastening plates. Use the Column component and Beam component sections to define the fastening plates in the column and beam.

Select the following option in the Connecting devices list:
In the Custom list, select Yes.
Click the ... button next to the Component field to open the Select component dialog.
Browse for the custom component you want to use as fastening plate.

The component you select must be a custom part and have two or more input points.
Select the component and click OK.
To use saved custom component properties, select the saved properties file in Custom settings.
If the direction or rotation of the fastening plate is not correct, select another option in the Up direction or Rotation list.
