# Tendon \[TB] Tendons can be modeled for concrete substructure elements of the truss bridge. In the Truss Bridge workflow, tendons can be defined for: * Pier caps and bents (Cap/Bent Tendon) * Pier columns (Column Tendon) To use the Tendon objects, the user must have a previously defined or imported Strand Profile under the Properties section. If a user does not have any strands defined, it is recommended to return to the [Strands \[TB\]](/templates/truss-bridge-workflow/properties-tb/strands-tb.md) section of the workflow, define the related strands, and then proceed further. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
