Earlier quoted context omitted.
In that project farm video, the screws came out stronger than nails in every test except the repeated bend test (even the drywall screws). I think it could be argued that since screws are much stronger and have better holding power, they are much less likely to get loose enough to the point that they are going to be repeatedly bending back and forth.
I think this is valid -- I'm not a structural engineer so I can't speak to how an earthquake might behave differently than the tests in the Project Farm video, but I can imagine a scenario where a screw becoming a bit loose would create a situation that more closely resembles the repeated bend test. The IBC still outlines nails as appropriate light frame fasteners [0], and where I am (on Maui) there's no local provis…

#321I definitely don't know for sure. But one thing I do know for sure, is that a lot of official building code is not necessarily based on careful scientific study but rather on "that's the way we've always done it".
