Create a concrete polybeam

Create a concrete polybeam

A polybeampart of a certain shape that is created as a continuous chain of beams passing through points that the user picks

The segments of the polybeam are straight, but segment intersections can be curved. For example, a beam that follows a zigzag line is a polybeam.

can contain straight and curved segments.

  1. On the Concrete tab, click Beam > Polybeam.
  2. Pick the points you want the beam to go through.
  3. Click the middle mouse button.

    Tekla Structures creates the beam between the points you picked, using the Concrete beam properties in the property panecontrol element in Tekla Structures user interface in the form of a side pane window

    The property pane can be used to show and modify the properties of model objects.

    The property pane can be customized by using the property pane editor.

    . Note that you cannot create a closed polybeam.

  4. If you want to create curved segments, chamfer the corners of the polybeam.

    For example:

Modify concrete polybeam properties

  1. If the property pane is not open, double-click the polybeam to open the Concrete beam properties.
  2. Change the properties as needed.
  3. Click Modify.

Concrete beam properties

Use the Concrete beam properties in the property pane to view and modify the properties of a concrete beam or polybeam. To open the properties, double-click the polybeam. The file name extension of a concrete beam property fileobject type specific file that contains values of properties or settings used in the property pane or a dialog box

Property files are saved in the current model folder. The user can create and modify property files and copy them to the project or firm folders for future use.

User-defined attributes related to a specific object type are stored in a separate property file.

is *.cbm.

If you have customized the property pane layout, the list of properties may be different.





User-definable name of a beam.

Tekla Structures uses part names in reports and in Document manager, and to identify parts of the same type.


Profile of the beam.


Material of the beam.


Type of finish.

Finish is user-definable. It describes how the part surface has been treated.


Use to group beams.

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


On plane

Beam's position on the work plane, relative to the beam's reference line.


Rotation of the beam around its axis on the work plane.

At depth

Position depth of the beam. The position is always perpendicular to the work plane.

End offset


Change the length of the beam by moving the beam end point along the beam's reference line.


Move the beam end perpendicular to the beam's reference line.


Move the beam end in the z direction of the work plane.

Curved beam


Plane of curvature.


Radius of the curved beam.

Number of segments

Number of segments Tekla Structures uses when drawing the curved beam.

Cast unit

Cast unit numbering

Part prefix and start number for the part position number.

Cast unit

Indicate whether the column is precast or cast in place.

Pour phase

Pour phase of the cast-in-place parts. Use to separate pour objects from one another.



Use to warp beams using deformation angles.


Use to pre-camber beams.


Use to shorten beams in the model. The true length of the beam is decreased in the drawing.

Concrete covers for rebar sets

Coordinate system

Select whether the concrete cover thickness of the rebar sets in the part is defined in the global coordinate system, or in the part's local coordinate system.

The default global and local cover thickness values are defined in the Options dialog box.

If you select the empty option, Tekla Structures uses the global values.

Top, Bottom, Sides, Front , Back, Start, End

To override global or local default values from the Options dialog box, define the cover thickness at each required part face.



Click the User-defined attributes button to open the user-defined attributes (UDAs) of the part. UDAs provide additional information about the part.
