If you taper 2" or notch 2" off a 9" joist, it performs as a 7" joist,
I have quite often designed glulam beams with cut outs at the end - say to go in steels etc.Really!?
What you mean 200mm from top and 150 from bottom?
True story bro.Really!?
So you're saying that if you have a 9" deep joist and notch it 2" at the end, you've turned it into a 7" deep joist??? Hmmm...True story bro.
Cut outs from the middle?I have quite often designed glulam beams with cut outs at the end - say to go in steels etc.
The structural Engineer always passed them - he did tell me once how big a chop out is possible - it's quite a lot, something like a 1/3 (can't remember the length) before it lowers the beam stiffness.
Did I say that?So you're saying that if you have a 9" deep joist and notch it 2" at the end, you've turned it into a 7" deep joist??? Hmmm...
Cut outs from the middle?
Or cutting the top or bottom edge?
Apology accepted.Silly me - my most sincere and humble apologies - I mistakenly thought you said:
"If you taper 2" or notch 2" off a 9" joist, it performs as a 7" joist"
