We have a new home and the floor vibrates some and may have a little bounce. I don't notice the bounce per se, but do notice the vibration. (Our builder went bust, lots of problems, but not for this post).
36ft span, with 2x4 supporting wall at midpoint.
LPI 20 plus i-joists 11 7/8, flange is 2 3/8. 16" oc.
Open from below.
Obviously I wish the floor was supported with beams and posts, but I don't (didn't) know anything.
I don't believe it is a significant structural problem, more something that iritates me and does not feel high quality.
What solutions would you recommend?
1) I am giving serious consideration to bridging. Would this make a noticeable difference? I have stumbled on the this product called IBS 2000 Connectors by Luxocorp. Anyone familiar with it, would it be better than something I get from local lumber yard or big box? It is more expensive.
Do I need to do something more dramatice and expensive--beams and posts? strapping?
