thread507-299861: ASCE 7-05 - wind corner zones
I read this thread from ASCE 7-05 and it seems the answer was still up in the air concerning any definitive word from ASCE on the matter so im re-posting the question for ASCE 7-10.
Are Inside corners and valleys considered End Zones or Corner Zones?

RE: Asce 7-10 Corners
Ends and corners get special treatment because of various considerations, like vortexes that form at edges. An inside corner of a wall (not near an end) would see positive stagnation pressure (same as center of a long wall), and no real potential for negative pressures greater than would be seen at the center of the same long wall.
On a roof, where air is flowing across the surface, a valley could result in an increase in air speed across the valley (same air has to travel a longer distance) resulting in a sudden decrease in pressure. This can result in increased uplift.
