I'm getting ready to install my subfloor, but I am considering stiffening up the joists with some bridging
first. 2 x 6 joists installed 18.5" O.C. +/- 2 inches (old house, they weren't too exact). There's no blocking/bridging installed today. The joists are 20 feet long spanning 8 feet from beam to beam.
There was a little springy-ness to the floors before I pulled up the wood flooring. But there wasn't any subfloor (just the oak strip flooring laid on the joists), so adding the 23/32 Sturd-I-Flor plywood will help quite a bit. The same oak flooring will be going down on top of the ply, it's in great shape.
I looked at simpson strong ties
and they may be my best bet but I'm concerned the uneven spacing on the joists will cause a lot of installation frustration. Can I use continuous metal strapping instead? I can't find any info on using continuous strapping for this, but it just makes sense to me.
Another option is simply adding more joists, which might be a good idea anyway since I don't have support at 48"/96" right now (I know I would need to cut the ply to fit).
Would love some of your experience on how significant an improvement adding bridging is, or if it wouldn't be worth it for 8' spans.
