Hello. I can help
Will they support any ceramic tile or other brittle floor finish?
Thank you. Give me a few minutes to run numbers
3.5" x 9.5" 2.2E LVL at 12" on center is the most shallow you can go
You do run the risk of walking induced vibration problems going that soft on such long floor joists, but they work for strength and deflection
It just barely works at 16" on center. It's right at the deflection limit and is more likely to be a problem for vibrations
Hello. Do you have any other questions for me on this topic? If you could rate my answer, I would appreciate it.
