I think you have a reason to be concerned. Search the internet using
google. I think you will find many stories of gusset plate failures when
used in floors. Ok for roofs but I would never have a floor built that way.
One story I read a while back was a condo that they had to rip out ceilings
and sister every truss with a solid beam. It is going back a few years but
if I remember correctly the original manufacturer who had invented the
system had misrepresented strength and engineers had been relying on those
numbers when designing floors.

question on trusses. contractor is building a stand-alone garage
24'x30'. 2nd floor is for storage. he's using 2x8 lumber for the floor
joists, mated in the middle with a gusset plate.

is this sufficient for bearing weight on the 2nd floor for storage?
some reason I thought wood-composite i-beams were better. he said the
gusset-type should be fine.

yes? no? opinions?

is the 2x8 part of an attic truss? if so, then they would be
engineered and will be fine. I joists might support more load, but I
assume the project has some budget---I joists would require second
floor framing or perhaps a hand framed roof, all more expensive.
