Porch Uplift
Porch Uplift
(OP)
I know this is open for interpretation a bit, but would you consider a porch an roof overhang in regards to designing uplift?
Code ASCE = 7-05
roof pitch = 4
V = 100mph
Exposure = C
Also, when figuring GCPi, would you consider the structure to be open on partially enclosed?

Roof overhangs have their own calculation and i want to say that the values from this are similar to obstructed open profile mentioned above.

So I would consider it to act like a roof overhang or as a separate open structure. the loads shouldn't be too much so a little conservative calcualtions shouldn't hurt your design much
