Travi fuori spessore

I just cannot believe there is no such term in English :D

you don't need a specific term in my opinion; they are just beams whose footprint is outside the "thickness outline" of the surrounding structures

Exactly Claudia. I've been researching and found lots of different classifications for beams in English but no technical term to fit that specific description. L & T beams come close, but I need a collective term since the T or L shape depends on the location of the beam on the slab.

yes it's clearer now: it seems to mean that the "fuori spessore" beam would protrude beyond/come out of the outline (the "thickness") of the surrounding structures

Thanks Marco, you're right. The engineer who wrote the source text explains: "Trave che emerge sul piano inferiore del solaio." I'm not sure whether these beams would actually be "non-standard" or simply larger than that specific slab (I'm not specialized in structural engineering) . The paragraph: "As for the strands placed along the slab, we suggest the use of single-strand elements instead of 22-strand cables, the thickness of which would require travi fuoori spessore."
They also feature in another paragraph: "Vincoli torsionali sono realizzati con le travi fuori spessore a livello intradossale dei solai di cui formano una costolatura."

I think that posting the entire paragraph of the source text would help those who are trying to help you.
On the basis of the available context, one could guess that they are talking about beams of non-standard thickness, but this would be a mere guess.
