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

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

  1. Click the Applications & components button in the side pane to open the Applications & components catalog.
  2. Enter corbel in the search box.
  3. Select Corbel connection (14).
  4. Select the main part (column).
  5. 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.
