CFS: Solid Blocking, Tension Bracing or TradeReady Structural Blocking?

CFS: Solid Blocking, Tension Bracing or TradeReady Structural Blocking?

CFS: Solid Blocking, Tension Bracing or TradeReady Structural Blocking?

(OP)
A CFS joist elevated platform over an entrance vestibule.

Solid Blocking is not really part of the inquiry. Is has the greater strength of the three, and thus, the greater cost. For high pedestrian traffic I will specify it.

For the elevated platform over an entrance vestibule, there will be occasional human live load, on the elevated surface, to set up décor or whatever.

Are we confident that the Clark-Dietrich TradeReady Structural Blocking has the integrity of the Tension Bracing? Would anyone even recommend solid blocking in this case?

Other comments or suggestions?

Thank you!

RE: CFS: Solid Blocking, Tension Bracing or TradeReady Structural Blocking?

I always specify that every other joist be flipped. This lets the hard side of the joists face each other at 32" o.c. Then I specify a full-height joist piece for blocking fastened with a Dietrich E series clip at each end. By flipping the joists, their inherent instability due to their lack of symmetry cancels out.
I was on a job where the joists were spanning about 30 ft. - all facing the same direction. The whole thing came down as they were erecting it due to all the joist buckling in the same direction.
If you span are short, it likely does not matter what you use.
