Prestress Hold

[fabrrr]

Hello to everyone. I’m modelling a box girder bridge post-tensioned in abaqus 6.12, using a shell elements. For tendons, I’m using a truss elements, and I use TIE command for make interaction between shell and truss. For post-tension, I’m using a predefinied field-stress and i will want use a command PRESTRESS HOLD.
On the Abaqus's manual i read that i can use the command PRESTRESS HOLD just for the rebar, so do you know if i can use truss like rebar?

Thanks in advance.
