Rod x-braces & metal studs

[SperlingPE]

Generally the rod x-braces are in place before the metal studs for the wall are in place. So the studs get cut in order to get them in place. What are other engineers doing to repair the studs that get cut? I have a couple of details that I use, but want to see if there is a better way out there.

I have not run into this, but I would say using a 1-1/2" X 1-1/2" X ?? GA angle would make an acceptable splice. You would need enough screws each side of the cut to develop the flange force.

DaveAtkins' suggestion is basically what I've always used, but the metal stud guys will throw a fit. At least, that's what I constantly run into. I finally started using diagonal tubes and allowing the studs to be attached to them.

Atkin's suggestion is generally what I do. I also replace any portion of the web that is cut out.
I will use tubes if the loads are high enough. The contractor's are the ones to complain about the use of tubes vs. rod.
Any problems with drywall cracking that is attached to studs that are attached to the tubes?

To (attempt to) prevent drywall cracking, use slip track / deflection track / double track ...

Slip track works for vertical movement. The deflection of the brace along the axis of the brace is what I am asking about. I don't think that the tube brace would move enough to cause a problem?

I haven't run into this either per se, but anytime I've had to splice studs, I always check shear and deflection at the splice location in addition to moment. It doesn't do much good to have a splice handle the flange force if there is almost a hinge in the stud because there isn't enough moment of inertia at the splice. If there is enough room each side of the rod, you might be able to fit a small stud in there each side of the rod if angles don't work. Those help with the I[sub]x[/sub] more too.

Are you talking about axial shortening or lengthening of the tube being a concern?

 

[SperlingPE]

Axial lengthening and shortening, whichever could occur and its affect on studs directly attached to the tube brace.
