ASCE7-10 Wind
ASCE7-10 Wind
(OP)
I am using a spreadsheet called ASCE710W that I found on the AISC Steel Tools site. The notes in the spreadsheet say that Exposure D should only be used outside of hurricane-prone regions,and that Exposure C applies to water surfaces in hurricane-prone regions. I can't find this anywhere in ASCE 7-10, including the commentary. Can anybody shed any light on this?

The surface roughness and exposure definitions do not use the phrase "open ocean".
RE: ASCE7-10 Wind
Technically you are correct, but the entire logic of the discussion in C26.7 has to do with the surface roughness of the ocean. Under ASCE 7-05 I would use Exposure C because it applied to "ALL water surfaces in hurricane prone regions". Now, because of the surface characteristics of the open ocean, which has nothing to do with my situation, I have to use Exposure D. Makes a lot of sense, right?
