We have a project where we are trying to distinguish between frame and girder construction versus panel construction.
If we have steel frame and girder construction, beams are less than or equal to 7'-6" apart, but there is a corrugated deck that allows for heat flow above the girder (and wouldn't trap all heat), does this qualify as frame and girder?
Will the maximum deflector distance be 22-inches if there is a corrugated deck?
My assumption is "no" since heat is not capable of being trapped and a sprinkler needs to be placed in each bay within 12-inches of the deck.
