I doubt it.
Knowing about structures and being a practicing IStructE are completely different. So I'm not following your inference.
There is brutressing required in domestic internal walls.

What i think this boils down to is that brickwork is not good at resisting tensile forces, and it is these which horizontal wind load imparts on brickwork panels.
For this reason, brickwork panels, whether on multi-storey flats or low-rise dwellings, are limited in height and width. In traditional houses, room sizes have generally been limited by the spans available with timber joists. This results in relatively small-area walls enclosing a cell-like structure, where the walls at right-angles to the wind act as shear walls and generally provide overall rigidity.
Whether we call them shear walls or buttressing walls doesn't matter - the end result is the same.
Approved Doc A gives 'rule of thumb' dimensions for walls in traditional domestic buildings but these are necessarily quite conservative and can often be departed from on the basis of experience or analysis.

Yes, bit reluctant to enter this debate but in my experience SE would not need to design windposts for simple house extensions if you could comply with the requirements in AD A.
I would suggest that if someone needs to go in to someone's house to do a calculation to see if a wall is butressing or not, then they don't know anything about houses and should not be even let in to the house in the first place.
Those are the sorts of engineer that produce 20 pages of gumpf for a single beam instead of a few lines, and write pages of might be's and could do's instead of one paragraph of what is for a structural appraisal.

Hey, is this kid the new FMT after a 2 day structural course? I'm loving the clarity already.
Anyway it's occured to me that I'm actually commenting in the wrong thread. This is not the "internal wall removal" thread but a different one. LOL.
But my comments still stand ..... as does my house after all these years with its doors and windows right in the corners, and no posts and no calcs, and no butressing. It's voodoo I tell you, because I've not got a clue about structures.

I'm assuming the OPs supposed SE was not just some random off the internet. I guess you're using a circuitous way to tell the OP to listen to the professional onsite rather than you or I or anyone else on this thread!
