Would any of you guys have a problem with these I joists stacked on a lower I Joist? One room has an 8’ ceiling and the next room has a raised ceiling. The joists for the raised ceiling sits directly on the lower I joists. The higher I joists have squash blocks but the lower joists do not. Is this too much of a compression load on the lower I joists. Just my thoughts is that I Joist are not designed for much compression loads.
Don’t know if someone designed that, but in my opinion, they should have had a continuous bearing plate between the two tiers of I joist and either way squash blocks are required on the lower tier joist.
The 2x4’s on the upper tier are not correct, they are imposing a direct load on the I-joist blocking they used on the lower tier and squash blocks are already missing on that lower level.
Needs to be reviewed by the original designer if any or a qualified Framing Contractor.
Larry, please take a closer look my dear friend 
Those are not metal brackets, those are painted/stained/sealed ends of opposite I-joists resting on the LVL header. They used cut up pieces of I-joist as blocking in between to support the OSB used as subfloor, some “wonky” stuff going on here LOL

I agree and it is not right.
If they are painted ends of I-Joists, I agree that there is some “wonky” stuff going on.
Thanks for the help/correction, Simon.
I guess it is time for another eye check up. Four years ago, I had 20/20 vision with no stigmatism or cataract potential.
But, alas, the time is coming after the first of the year. LOL!
No issues.
IMO: It’s OK, provided they have the minimum required bearing. The lower joists have been well stabilized against lateral movement.
Of course, if it were my inspection, I always record the make and model of the joist so that I can verify anything questionable in the detailed guides that the manufacturer’s publish
Where are the plans?
Take a look. Any building/house with a floor system like that will have a special drawing just for that area and those components.
I’ve used Boise-Cascade floor systems and the lumber distributor has provided me a detailed drawing beyond my own architectural plans.
Yep, and tell you what to do when you put a load on the ends with another floor. Page 26 of
CS likely applies, however, the stacking of 2 I-joists is a unique design; like you mentioned, squash blocks alone won’t do the trick without a load carrying plate over the bottom joist.
Really? Many issues with this install.
