Rebar Coupler and Anchor Tools: Customize attribute files, part mapping and user-defined attributes (UDAs)

Rebar Coupler and Anchor Tools is a set of four components that help to model and manage
  • reinforcing barreinforcement that represents a steel bar used to reinforce a concrete structure

    The steel bars are usually ribbed and they are used to increase the tensile strength of concrete.

    couplers that connect two bars

  • end anchors that are devices at the unreserved end of the bar.

The following components are part of Rebar Coupler and Anchor Tools :

In addition, you can manage the user-defined attributes (UDAs) of the Rebar Coupler and Anchor Tools with the Rebar Coupler and Anchor Tools: Update rebar attributes component.

Auto attribute files

The attribute table files are text files that can locate in any of the system folders, or in a model folderfolder that is used for storing files associated with a model

Tekla Structures stores all files associated with a model in a folder it creates with the same name as the model database (.db1).

In multi-user mode all users access the same model folder.

. You can have as many attribute table files as you need. There are different attribute tables for end anchors (one input reinforcing bar) and coupler components (two input reinforcing bars). The extensions for attribute table files are

  • .couplers.csv for Rebar coupler and Split rebar and add coupler components

  • .anchors.csv for Rebar end anchor component.

The attribute table contains a header line, including the column names and one or more table rows containing the attribute values. Columns are either selector columns or attribute columns.

The selector column names are Primary.Size , Primary.Grade , Secondary.Size , and Secondary.Grade.

The attribute columns contain the attribute value that is the name given in the header row. The component attribute values given in the table row are used whenever the component input (primary + secondary for Rebar coupler and secondary for Rebar end anchor ) matches with the selector values.

Go to Tekla Warehouse to get auto attribute files for your project.

Custom part mapping

When you create the coupler or the end anchors as custom parts, the properties in the Numbering series and Attributes sections can be filled from the custom partcomponent for creating a part that cannot be created by using any existing part command or part profile

Typically, custom parts are used to create parts that have a complex composition. For example, castellated beams and sandwich panels are often created as custom parts.

settings if you have named the properties in a certain way. The following example shows the mapping between the Numbering series and Attributes properties and the custom part properties.

User-defined attributes (UDAs)

You can customize the content of the Attributes tab and the UDAs in the Rebar Coupler and Anchor Tools components.

The UDAs are defined in a text file named RebarCoupler.Udas.dat , located in the ...\ProgramData\Tekla Structures\<version>\Environments\Common\system folder. The file can also be placed in some other system folderfolder that is used for storing files that define default settings

or in a firm folderfolder that is used for storing Tekla Structures-related files customized for a particular organization

A Tekla Structures user can, for example, customize a company’s cloning templates and save them in a sub-folder located under the firm folder. After this, the customized cloning templates can be used in all projects carried out for the company.

. Note that the file is not read from the model folder.

The RebarCoupler.Udas.dat file only defines which UDAs are shown on the Attributes tab. If you modify the file, include only existing UDAs to the file. If you want to create new UDAs, ensure that you define them properly.


The UDAs affect numberingprocess of assigning position numbers to parts, cast units, assemblies, or reinforcement

In Tekla Structures, the position numbers assigned in the numbering are shown in marks and templates, for example.

if the UDAs' special numbering flag ( special_flag ) is set to yes in the objects_couplers.inp file. Reinforcing bars with different UDAobject property created by the user in order to widen the range of predefined object properties

User-defined attributes are used when the predefined object properties are not sufficient but more properties are needed. For example, comment, locked, and erection status are user-defined attributes.

values will then get different part marks.
