2.18.1 The “Concrete column” tool in Tekla Structures
The "Concrete column" tool is similar to the "Steel column"
tool. Let’s create a concrete column by enabling the respective tool
at the main menu bar and pointing out its location at the view.
Tekla Structures v21.1
Tekla Structures v2021
Create a steel column next to it and simultaneously open the objects'

Tekla Structures v2021
As you can see, the objects' "Properties" windows are defined

Tekla Structures v2021
The only difference between these objects stands for "Numbering"
field parameters. In the older TS interface, numbering parameters are even
placed under a separate tab.
Tekla Structures v21.1
Tekla Structures v2021
Let’s make sure that all the other parameters are similar. Go to

Let’s investigate the “Deforming” section.
Tekla Structures v21.1
Tekla Structures v2021
The only difference between these column types is that the concrete column
is not available at numbering series parameters, such as "Part numbering"
and "Assembly numbering", as concrete parts can not be welded
on into an assembly.

Superseding the material type from steel to concrete, and vice versa.
One of the most important characteristics of all steel and concrete modeling
tools is that they are interchangeable. Thus switching the material type
of a steel column to any available from the concrete material catalog automatically
changes the object’s properties as it was initially created using
the “Concrete column” tool. Similarly, the converse is also
true.
Close the "Concrete column Properties" window.
In the "Steel column Properties" menu modify the material field
parameter to any concrete grade.
Close the "Column properties" window.
Tekla Structures v21.1
Tekla Structures v2021
Repeatedly open the "Column Properties" menu. As you can see,
the "Properties" window from now on is defined by the concrete
column object type. The column's I-beam shape remained unchanged, though
it is exactly the concrete column. See below:

Go to the “Cast unit” section. Note that the "Cast
unit numbering prefix" was transferred from the "Assembly prefix",
but the "Part numbering" field has disappeared at all.
Tekla Structures v21.1
Tekla Structures v2021
The "Cast unit" field
defines the parameter which is characteristic only for concrete objects.
It is necessary for providing compatibility between various license types.
New license types are no longer containing this parameter, though Tekla
Structures is still available on such a field. We will examine in detail
this parameter functionality when getting to the SST drawings chapter.

Toggling between the cast unit values does not affect the model in any
The profiles of concrete elements are
completely different from the respective profiles of the steel elements.
When modeling steel structures it is not recommended to use parametric
profiles as they do not contain ISO specifications, according to which
objects should be manufactured. Concrete elements are not bought-out components,
thus it is recommended to use parametric profiles while modeling concrete
objects. The rectangular sectioned profiles are of frequent use. Let’s
try out writing into the profile field value of “
600*400
”.

The round cross-section columns are defined by the profile names which
