Tek Screw Shear Fastened Thru 5/8" Sheetrock 2

[XR250]

I have a situation where I need to fasten a light gage track to a stud wall thru 5/8" sheetrock to resist shear from gravity loads. I am trying to avoid this, but my client is pushing me to at least do some research. Does anybody know of any testing data that has been done for this condition? I already called Buildex and while they recognize that this comes up alot, they have no testing data.

Thanks

I think all of them

wannabe - It's awesome when we can find "ALLOWABLE" load tables to "support" our designs. However, those tables will not support our liability when / if the system fails.

XR250 - But, i hesitate to use this ESPECIALLY for a floor system.

I fail to see where fixity can be obtained with any cantilevered TEK to CFS unless you weld it. Even then, will the CF hold up? Perhaps! But my thought of welding seems impractical. I never design any CFS to CFS unless there is intimate contact. Especially for a floor system.

Who is installing the screws?

Are you going to inspect each screw installation?

Think of the weakest link...

I totally agree. Def. not using it for the floor. But for my soffit with only 70lbs wind load, I do not feel too bad about that.
