I am in the process of designing a backstop for a high school athletic
field. 100mph wind loading, 27'-5" high. I determined my wind pressures
using ASCE 7, assuming an epsilon of 0.192 (2x2 6 ga. mesh). My average
wind pressure (total force over area) came out to be around 17.7 psf, which
for a cantilevered 27.5' post at 8' or 10' is huge. I was originally
assuming I would have 4" diameter schedule 40 post at 10' on center; but now
I'm coming up with 8" A53 pipe at 8' on center. Am I missing something?
