Hi. A question has come up and I can't get an answer from Simpson Stongtie
until Monday. Does anyone know if there is a problem with using metal framing
connectors on top of the plywood sheathing? I haven't found an answer on the
Simpson web site - just one reference showing a strap tie on top of sheathing,
nothing that says that _all_ connectors can/could go on top of the sheathing.
Anyone have a definitive answer or know the applicable section of code?

Reason I'm asking is because I need to get the building closed in ASAP and the
building inspector won't be around for another couple of weeks. Someone should
have warned me winter was coming!

Thanks in advance.

Have a Happy Thanksgiving everyone.

Rico;

It would depend on the configuration of the framing connector wouldn't it ?

If it's one that requires fasteners in 3 dimensions (ie joist hangers, framing
anchors) then I would say "no".

OTOH, if it's one that simply requires fasteners in 2D (ie straps) then "yes".

I'm not sure I follow about the 2D-3D stuff. Can a joist hanger be nailed
through plywood sheathing or must it be nailed directly to a rim joist? I'm
guessing it's not a problem, but I don't know what the IRC says about it.

Well, I have no idea what your inspector will require, but I've
installed tie straps over sheathing before and don't see any problem
with it structurally assuming you are talking about installing the
straps over a 2X structural member and nailing through the sheathing
into the 2X. If you are talking about just nailing into sheathing and
nothing else, then I think that's a big problem and I can't imagine that
passing inspection.

Hey Matt. There will be, of course, framing members and not just sheathing.
Part of it is that the load path requirement requiers that the metal connectors
be on the same side of the framing members - I guess that's so the member
doesn't act as a hinge. Since this is a remodel both sides aren't equally
accessible and it makes a difference in being able to close in the building.
The inspectors around here have gotten a lot tougher and I just wanted some
ammunition in case he calls me on it.
