I have reviewed the above noted structure for a wind load pressure created by a
100 mile per hour wind velocity. See the following calculations.
P Ce Cq I qs
C = 1.2
e
C = 1.3
q
I = 1.0
qs = 26
P = 1.20 .3)(1.0)(26) = 40.56#/sf
The structure had originally been designed for 32#/sf by a California engineer/
architect and I increased the nailing of the plywood sheathing and also the size of
nails from 8d to 10d. Although the wind pressure has increased appreciably it is
my engineering opinion that the structure can take this increase in wind load.
