I guess I should mentioned the Min. 19/32" wood structural sheathing above the
joist with lightweight concrete above the sheathing. Does that make a
difference?

There is a one hour floor assembly which consist of 22" Red-S joist (Wood
Chords with Tube Bars) with 2 layers of type x gypsum board on channels below
joist. Could it be considered limited combustible construction inside the bar
joist? Or am I just grasping for straws, and it needs sprinklers.
