ASCE7-05 Components and Cladding wind pressure buildings greater than 60 ft
ASCE7-05 Components and Cladding wind pressure buildings greater than 60 ft
(OP)
I have a building with a footprint of 170 x 130 by 400 ft tall. V = 105 mpf, I = 1.0, Exposure "B"
The wind load program I use gives me a components and cladding corner design pressure of 70 psf and a non- corner pressure of 38 psf
My task is to design curtain wall support members near the corners from elevation 0 to 30 ft.
Do I need to use a design pressure of 70 psf at this location? Seems a bit excessive?

I MAY BE INCORRECT, THE HEIGHT VARIATION IS MWFRS. SEE THE SMARTER PEOPLE BELOW TO CORRECT ME

In summary, my mistake I must have been thinking MWFRS at the moment.

These numbers drop to 42 psf and 31 psf respectively for larger effective areas.
I get positive 21 psf at zones 4 and 5 for small areas and 16 psf for larger effective areas.
Positive pressures are affected by actual height and mean height while negative pressures appear to be based on mean building height.
