Default Re: Acceptable lateral support for ceiling joists?

Gordon, I'm not good w/ it. this in reference to your statement above.. You've got the strongback laying on top of the ceiling joists in your last pic, but how well are they fastened? There's obviously no fasteners up from joists to the strongbacks as seen in pic. Even if strongbacks are properly fastened from above and down into, which we can't even verify from pic that is from below, the joists should have fasteners up thru them into strongback(s) to help w/ future seperation. Nails (unthreaded like screws) pull apart, that's why they should be nailed from both sides, for instance just as joist and rafters connections should be nailed together on both sides that are sitting on an exterior wall- to help prevent seperation.
