IRC 2009 Table R404.1.2(1) requires one #4 cont. bar 12" from the top of the found. wall and one #4 bar near mid height of wall. This is for wall heights less than or equal to 8'.
My thought is that hor. bars in a foundation wall give the wall the ability to act as a grade beam to help bridge...
Thanks IdeCharlotte for your response. It seems like you are in agreement that something needs to be specified for larger spans.
Anybody else have any input or experience with the Simpson skewed and sloped hangers?
Toad Jones - that's what I'm talking about and the type of response from framers.
Up to what size roof do you think it's OK to do it traditionally?
What if the main ridge is 30' long and the intersecting ridge is 16' long and the snow load is 40 PSF?
I've been tackling this issue for a while now and have had some discussions with builders regarding these connections.
Best way to start this discussion is to view the following video:

I'm set on using Simpson Hangers for this...
From my experience, most framers toe nail first and then go back and put the hangers in if they're specified. This is true for joists and rafters. Hangers just slow them down. They need to get the framing up and weather tight ASAP.
If you have a 5:12 pitch, 2x10 rafters at 16" spanning up to...
take a 2x10 rafter attached to an LVL ridge w/ 5 good toe nails ea. side w/o splintering the rafter. Test load it and see what you have for an ultimate capacity. It will probably be around 1800 lbs in shear. Divide that by a SF of 4 and you should have about a safe load of 400 to 500 lbs.
I...
Design delegate the connections. Put the reactions on the drawings. Connections are detailed with computer software by the detailer anyways. They have the ability to design and detail them most economically.
Plus we wouldn't get the job if we included connection design. Our competitor's would...
If it's a ridge beam, then you don't need collar ties.
Toe nails are perfectly acceptable per NDS. There is a reduction in shear capacity. You should be able to add enough of them to obtain the capacity.

I think if you're designing LVL's, steel beams, etc. in a complicated large residential home that eventually you will make a mistake that will come back to bite you.
There's no way you can design a complicated home properly and economically speeding through half baked quick...
