# Tendon \[CBG]

Tendons can be modeled for the concrete box girder bridge elements. Both girder tendons and cap/bent tendons are supported.

To use the Tendon objects, the user must have a previously defined or imported strand under the Properties section.

If a user does not have any strands defined, it is recommended to return to that section ([Strands \[CBG\]](/templates/concrete-box-girder-bridge-workflow/properties-cbg/strands-cbg.md)) of the workflow, define the related strands, and then proceed further.
