The perimeter upstand beam in a concrete (or other) frame which helps support the edge of a floor slab.

Its a multi-storey building with ribbon windows. The wall below the windows is part of the structure. If I cut this, the floor will probably collapse, but I can’t remember what its called!

Also, can I have the number for the early-onset alzheimers helpline, or at least another cup of coffee please 😀

:cue lots of frantic googling by people who are not structural engineers:

Ring beam?

Not ring-beam. It has finally come to me however. Kudos to the first to correctly guess!

a sleeper wall?

(That’s a guess, i’m not a structural engineer btw 😉

Was going to say ring beam.

Perimeter Upstand Beam

Jim Beam?

From conversations recently on something I’m working on they’re apparently also very inefficient compared to a downstand beam.
We might be going for a fat slab to gain 350mm per floor (overall depth).

it’ll be something like flange, gusset or clunge.
you know the dirty mind structural engineers have

member is a good one to get in as well.
