Re: Another ASCE 7-05 Wind Load Question

There was a clarification in ASCE 7 in the commentary back around '98 or '02, I think, which described cat b in much more generally applicable terms, implying that category C was less common than previously taken by engineers. I remember sitting around with the other engineers in the office and looking at the photos, which were key to the discussion, thinking the same thing you are now. 

FWIW, I've never seen a manufacturer voluntarily produce data for anything other than exposure B.

Is Exposure B the same as Exposure B in the 1997 UBC? It sounds like Exposure B in ASCE 7 is applicable in typical suburban/urban areas. OTOH, I’ve never been able to get UBC Exposure B to fly here without rigorous hoop jumping.
