2.7.2 Distinctions between a column and a beam in Tekla Structures
Generally, the beam and the column tools properties lists are similar,
Open the beam tool properties window. As you can see, there are a lot
of similarities among them.

The “Deforming” section parameters are absolutely identical

Below you can see the main distinctions between these tools framed with

A beam may have an upright and horizontal orientation thus there are no
The “End offset” fields
allow shifting a beam in 3 distinct directions with reference to a segment.
Note that this attribute is not to be used for moving a beam. A beam itself
has its local coordinate system. The X-axis is directed from point
1 to point 2, and specified by the user during drawing up a beam on the
view.
The "End offset" tool can be applied for both points of a beam:
Tekla Structures v21.1
Tekla Structures v2021
Exercise setting up the end offset value by Dx for the starting point
at 2000 mm. Thus, the yellow point of the beam (starting point) shifted
along the X-axis at 2000mm.
Tekla Structures v21.1
Tekla Structures v2021
Exercise setting up the end offset value at 2000mm. Note that the point
Tekla Structures v21.1
Tekla Structures v2021
The "End offset" values can be negative thus shifting a beam
Set up the value of -2000 mm for the endpoint Dx field.
The endpoint shifted into the opposite direction of the axis X.
Tekla Structures v21.1
Tekla Structures v2021
Restore the X-axis fields values to 0.
Tekla Structures v21.1
Tekla Structures v2021
The Y-axis is constantly perpendicular to the X-axis. Set up the Dy field
Tekla Structures v21.1
Tekla Structures v2021
Set up the same value to the respective Dy field.
Tekla Structures v21.1
Tekla Structures v2021
Setting up the values of the Y-axis to negative values shifts the beam
Tekla Structures v21.1
Tekla Structures v2021
Restore the field values to 0.
Tekla Structures v21.1
Tekla Structures v2021
The Z-axis is perpendicular to the other axes. Set up the offset value
for Dz at 1000mm.
Tekla Structures v21.1
Tekla Structures v2021
In the meantime, indicate the offset values for start and end points by
Tekla Structures v21.1
Tekla Structures v2021
It is important to mention that essentially, the "End offset"
and the "Position" tools execute the same function, though, the
"Position" tool displaces all the points of an object simultaneously,
but the "End offset" tool executes a selective displacement of
the points.
In practice, the "End offset" tool is not of frequent
use. It allows extending the beam ends, which is seldomly required, in
the time when the "Position" tool allows rotating an object.
Tekla Structures v21.1
Tekla Structures v2021
Exercise by yourself to set up various values to the “End offset”
fields to examine the tool's functioning. For further convenience,
let’s not use the "End offset" tool in the foregoing exercises.
The Curved beam “Radius” and “Number of segments”
We had already examined how to camber an object in the previous chapters.
Here we would like to mention that the “Radius” attribute of
the “Curved beam” section also allows cambering an object by
specifying the number of segments. Note, that using this attribute is reasonable
just in case you are importing or exporting data from calculation programs,
which allow adding intermediate points on a rod.
Create a beam of 6000 mm, and specify in the "Radius" field
Tekla Structures v21.1
Tekla Structures v2021
Setting the number of segments equal to 1, makes the TS automatically
convert it to 2, as if the number of segments is less than 2, then the
object is a simple straight beam.
Tekla Structures v21.1
Tekla Structures v2021
Indicate the number of segments equal to 3. Check the result. Note that
in practice, this tool is not used for cambering beams.
Tekla Structures v21.1
Tekla Structures v2021
Maximizing the number of segments still does not camber the composite
segments, those being straight beam fragments. But preparing models
for calculation might benefit from using this tool.
Tekla Structures v21.1
Tekla Structures v2021
Setting up the curved beam "Plane" value cambers a beam into
any direction required. Exercise all the options available in the drop-down
menu of the “Plane” field.
Tekla Structures v21.1
Tekla Structures v2021
Restore the default field values to avoid creating new beams possessing

Note that the saved settings configurations of the Column tool are not
applicable for beams, and vice versa so far as will not be available for
selection in the drop-down menu, even if the configurations titles assigned
are the same.
