Cb for Roof in Uplift
Cb for Roof in Uplift
(OP)
I have read in various places that you can use a Cb = 2.0 for a typical roof beam in uplift that is braced on the top flange by a roof deck. I believe it is based on work by Yura. In the places that I read/heard about this, it was presented such that structural engineers can use this value for Cb in actual design.
However, I have never seen this mentioned any type of governing document. Basically, I need something I can easily reference to justify my use if ever questioned. Even if I find the technical paper where this was first presented, this doesn't mean that the work is officially accepted by the governing code.
Thoughts???

Honestly, overall, I don't think they're all that useful. I've tried over the years to get a firm grasp of stability bracing using these notes and am still unable to really apply App. 6. I've been a steel and stability guy for some time, so I have to think that most folks are in the same boat. There are some good nuggets of info in there, like this Cb business, though.

Unfortunately, I don't know anyone with these notes.
