Is W6x9 laterally braced
Is W6x9 laterally braced
(OP)
I have a 20 feet long W6x9 supporting 1.5 inch (rib) 20 gage metal deck. Deck is screwed with top flange of W6 with #12 x 1 1/4" Tek Screws @ 12" O.C.
Now is compressive flange of W6 is braced laterally or not for designing purposes.

Isnt the 2% force supposed to be based on 2% of the compressive force at the top of the beam under full downward load?
I don't think its right to take 2% of the vertically applied load??

20 ft / 0.5 ft = 40
You could have a deflection problem.

When I've wondered about this myself I followed the procedure outlined in the steel book by Salmon and Johnson, and checked the KL/r of the deck < 200 (spanning to the next beam or joist), and found that the deck met those criteria for bracing.
