Maybe so, but here's the thing: if you apply the seismic load factors (as you're supposed to in the building code) to standard details from companies like TJI, you'll be shocked to find that their "pre-engineered/pre-approved" details aren't adequate. I've been shown where the value of a 10d nail is less than what's assumed in details that compose a lot of what we've taken for granted as "good or best" practices. Having a structural engineer review the load bearing capabilities (dead and shear) of the framing and the specific spot loads of the anchorage is a really good idea. And it's not just seismic, it's dead loads too. If I was an AHJ starting a new prevention bureau, it might be the first policy bulletin I issue.
