50mm deep in 150mm joists x6, 3m span, 300mm from end!Got any more context?
What size joists? What size notches? Where abouts in the span? Is it one or two joists or every single one, midspan, holding a tiled bathroom?
Lol, not in this realm of reality.They might ask for justification from a structural engineer…
BC come to us with all sorts of questions these days…Lol, not in this realm of reality.
300mm from the end it’ll be fine. Close to the middle it might be a problem.50mm deep in 150mm joists x6, 3m span, 300mm from end!
As stated it will be OK, assuming the timber was 100 x 60 the shear stress would be 0.5N/mm2 whilst allowable is 7N/mm2 so theoretically structurally OK for shear which is what its all about at beams ends. Convincing BC if they pick it up ??300mm from the end it’ll be fine. Close to the middle it might be a problem.
Don’t inspect notches? So why do we pay for there service!? The floor falls through who’s liable….Inspectors don't inspect notches!
However, the question should not be "will this fail an inspection" but "will the floor joists collapse in a few years when my extension has passed, the timber stabilised and the floor loaded"
