L/D Ratio - Floor trusses
L/D Ratio - Floor trusses
(OP)
What or who is supposed to govern Length to Depth limits? I can't find anything in the IBC. I remember only as a rule of thumb that L/D should be less than or equal to 20.
Your thoughts?

RE: L/D Ratio - Floor trusses
That said - be aware that some unwanted vibrations may occur with that ratio, especially if there are no walls or partitions above.
Walls/partitions perpendicular to floor trusses will generally deaden vibrations.
I generally try to stay with about 1/18 unless walls are involved.
And remember that strong-backs do help - but not all that much.
Just my 2 cents
