Based on the diagrams I found, I think you'd want to include 'eaves' in the translation.

Traditional British roof trusses do include short horizontal members like joists running in from the eaves. However, the common form has the eave projecting hardly at all, and these members extending across the thick masonry of the wall. Far from being indirectly restrained at the inner end, in the manner described above, there is a short strut known as an 'ashlar piece' running vertically from this inner end up to the rafter or raking roof principal. What is created is merely a small triangle resting
on the wall member, and the base of this is better described as a bearing plate than a joist. The same basic system is found in Australia, probably far more commonly than eaves joist construction, and two examples are the barn at 'Caoura'

Ashlar Piece: Short vertical strut near the foot of a rafter, joining it to a sole piece at the top of a masonry wall.
