ASCE 7 C&C
ASCE 7 C&C
(OP)
I am trying to figure out exactly when to apply the zone 5 C&C pressures to my wall in accordance with ASCE 7. I have a wall that turns 45 degrees. Do I apply zone 5 pressures here or would you still use zone 4 pressures? What angle do you begin to use the zone 5 pressures?

Wind to North would cause Zone 5 in the "underscore" wall
Wind to West would cause Zone 5 in the "slash" wall

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.
RE: ASCE 7 C&C
What they are trying to say, without actually saying it because that would make the standard worthless, is that the models used to develop ASCE 7 were rectangular. You have to use engineering judgment to use the standard in the real world if you don't wan't to tell your client that you need a wind tunnel for every project.
In other words, it is probably best to lean to the safe side and use the higher pressure coefficient.
Just sayin...
