How long have they been notched for?

Could be the same as 'how long have you been driving without a seat belt'

There's a reason, surely

So what do you think is suddenly going to happen now that has not already happened in the last couple of decades then?

Well, you never know, if I have a party and there's one too many fat chicks......

 

[freddiemercurystwin]

why would you let fat chicks come to your party?

Sometimes you have to take just what you can get.

If the clear span sleeper wall to sleeper wall is 2.8m, I suspect your 4" joists are already over-spanned. I usually work off the old (pre-TRADA) span tables, which are more generous than allowed now, and even these show only 1.87m for 4x2 @450 centres.
Also, your notching is not that near the end, and you will therefore be effectively weakening the joists further. If you have to notch on alternate joists, do as the others have suggested and strengthen with 3x2 glued and screwed on the sides. These pieces do not have to go the full span of the 4x2 - 4 or 5 ft long pieces would be OK so long as they are firmly fixed.

Ahh. I just had a proper look under t' floor. The span is actually 1.45m. What do you think, not as bad as we previously thought?

 

[SaladFingers]

Right. Well I've braced them all with treated 3x2's. Each end of the timbers are resting on the sleeper walls, just as the joists are. Then using M8x100 coach screws along the length.

I can actually feel the difference from walking across the floor.
