flood vent requirements
(OP)
If one can demonstrate a wall is capable of withstanding load from hydrostatic flood pressure do building codes and/or asce 24 still require flood venting?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: flood vent requirements
I don't believe you are correct. As I understand it, in V zones flood vents are not allowed. Even the literature you submitted says that walls below the BFE in V zones must be "non-supporting breakaway walls".
So the question is again, what flood zone are you in?
RE: flood vent requirements
I have worked in different flood zones and with different types of bodies of water. Along rivers they don't want you to impede the flow at all at flood elevation. I did a project in SW FL on a bay and the structure needed to be 10+ feet above grade, 10+ feet of scour for the piles, and I think only stairs and maybe breakaway walls in the flood zone. Recently I did a couple of analysis projects of houses adjacent to lakes where you are dealing with a slow rising flood and hydrostatic forces could be designed for or you would need flood vents (or soil supported slab on grade with stem walls so that the soil counteracts the water).
