LONG FLOOR JOIST SPAN

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Hi
I would like to know if I have 28 ft to 30 ft span
I use 18 inch or 20 inch TJI at 16 inch on center
I any one has experience has a problem with

1- vibration
2- noise
and how to limit that
even if I limit the deflection to less than 1/2 inch

thanks in advance
