RE: Deflection

I’ve typically seen people use H/400 for code-level (50-yr) wind or H/500 for 10-yr wind.  These end up being pretty close to the same.  AISC Design Guide 3 has some guidance.

When wind governs in your lateral system design, what is the building drift limitation?  There doesn’t seem to be any specified building drift limitation for wind loads (that I can find) in the code.  What do you wind country folks do?
