ceiling lower than eaves

Not the latest hi tech solution but a U shaped wrought iron bar was used to do just that in my house 400 years ago and it is still holding strong. Bet it doesn't meet building regs tho

IANASE.

You can put a beam or wires to tie them together at eaves (or higher) level. You could tie the eaves to the low down joists using modified/specially designed "gallows" brackets, assuming they run the same way as the rafters.

Why do you want a lowered ceiling ? But if so, you could have a look at commercial false ceilings which include insulation.

I have all ceilings like his: Upper storey floor is a meter below eaves. Ceilings a are a meter above it.

Structural engineers suggested all ceiling joists bolted to rafters, and all floor joists bolted to stud uprights. (its a timber frame).

so floor and ceiling joists all in considerable tension.

Oher methods suggested were fabricating U shaped steel sections to be buried in walls to take tensiles sttresses and connect the two walls.

I was wondering about that, but I see one possible issue. As the joist bends it causes the top point of the steel triangle to move in and out. I dont know if the amount of movement involved would be an issue, but I wouldnt be surprised.

Lets say for example the joist is 10' long, and the steel triangle 1' long each way. For a max 10mm of joist bend, there would be a max 1mm movement at the roof rafters. I dont know if thats an issue or not.

Presumably where the triangle is tied to the brick wall at the bottom there would need to be a spacer between wall and triangle, so that the brickwork is not moved by normal joist bending.

Anna's U shaped ironwork sounds like a very good solution, and I cant think of any reason for it not meeting BRs, but it also sounds like a relatively pricey option. In fact thinking more about it, it would have exactly the same issue, though the iron might be much more rigid than wood joists. You say its doing fine Anna: is it a brick wall, or timber frame?

Timber frame. Extremely over engineered

that means it wont mind moving about a little: brickwork might object.

Your kettle rarely comes out right by the way :)

It comes out well on my computer (of course) but I use fixed width fonts. Its not a foolproof design and it doesn't work with some fonts

Maybe you are using a font it doesn't like? Or do other people have the same problem?

It works fine for me, but of course I use a fixed width font (Courier) with a newsreader in a terminal emulator. Even smileys get broken otherwise.

I thought it was a house with dormer windows (the ^^) and impressive chimneys (the |""""|) with some birds flying past (~~~). The // just confused me totally.

There's a kettle here:
