Those are inelastic limits.

David, Matthew:

Seismic drift limitations are often in the realm of H/200 (using 0.020*hx and a Cd=4)…why so much more stringent for wind?

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?
