SJI Horizontal Bridging terminations?

[bolt45]

Is there anything in SJI that requires horizontal bridging row to to be terminated with diagonal bracing up to the diaphragm?

I looked, but didn't see anything. Seems like you would need to bring the bracing load up the diaphragm.

If it is uplift bridging, it needs to be anchored to something at each end. This can be, amoung other things, a structural wall, or a kicker up to the diaphragm.

Continue the horiz. bracing out and into the wall that runs parallel to the OWSJ’s. You can’t just stop any bracing in thin air and expect it to be very effective. And, you don’t accomplish any effective bracing when you brace to another equally unstable member, they just move together in an unstable way. Put an x-brace in btwn. two interior OWSJ members to stabilize the system. Be careful putting an x-brace or diagonal btwn. the last OWSJ and a wall, because the wall doesn’t deflect vertically, but the jst. does. And, the x-brace or diag. will induce some nasty secondary loads.
