Wind load on s structure at peak of mountain
Wind load on s structure at peak of mountain
(OP)
I am looking at wind loading on a structure sitting on top of mountain in west region of the US. Elevation difference from top to flat ground surface is about 3500 ft. Looking at topographic factor, calculation in ASCE 7-05 (or 7-10) yields the topographic factor on the order of 2. This seems quite high, but just to get some idea or sense if this is reasonable. I remember seeing someone mapped out an island in Hawaii that has similar magnitude of topographic factor (1.5 to 2). Any opinions are appreciated as I am looking for a sanity check.

The wind conditions are going to change with the season, with elevation, and with storm conditions (as storms pass by, local winds will vary tremendously from the seasonal average) but they are going to be LOCAL. Get measurements for THAT MOUNTAIN, not a book-value multiplier for generic mountain in a generic state.

You may have some reduction due to the thinner air at higher altitude, and I think ASCE 7 allows for that as well.
