French term or phrase: Charpente à chevron portant ferme
This comes from a document on an inventory which has been carried out in the Pays de Loire region of France.

I have found the following definition in French, but am completely stuck for the English term.

Un chevron-portant-ferme est une pièce jouant le rôle d’arbalétrier et de chevron. La charpente formée de tels éléments est dépourvue de panne et porte directement la couverture.

Explanation:
This is the diagonal (arbalétrier) of the roof section of a frame .
Usually purlins would be placed between the frames and then the rafters (chevrons) fixed on top.
This is an American reference from A Timber Framer's Workshop Steve Chappell Fox Maple Press 1998 on which I based my own design.
Here in this house, I set purlins between frames using wedged dovetails
I would say, literally " That part of the load-carrying frame which acts as a rafter."
I hope this is useful.

Not entirely sure this is right:

Common Rafter Roof System – Roof structure consisting of regularly spaced roof members, which span from the roof ridge to the eave walls. Typically, common rafters are spaced 4’ on center
cf
Principal Rafter/Purlin Roof System – A roof system where large bent rafters (principal rafters) are connected to one another by smaller roof timbers called purlins. Purlins are typically spaced 4’ on center and have a dovetail joint on each end to secure them into the principal rafters.
