plywood shear wall using gage steel wall framing
(OP)
I am an engineer in Southern California looking for ICBO and LA City approval for a shear wall system consisting of plywood attached to steel studs with screws. I have a few projects ahead that will be ideal for such a seismic system, and I think it would be an improvement from the code approved nailed plywood shear panels to wood studs.
I know that there is Federal approval for just such a system, but it is only approved for seismic zones 1 and 2. My progects will be in seismic zone 4.
I am presently conversing with the manufacturer of Grabber screws to see if they have such an approval.
Simpson Strong-tie might also be interested; I am waiting to here from them. By the way, they just got LA City approval for various connectors for gage steel framing (RR25489).

As a result, we are forgoing the use of gage metal wall framing on our projects.
And so, my needs for this thread have been met. If anyone out there desires to continue this thread, feel free to do so.

"It appears that the gage metal is much less resistant to fire than conventional wood stud framing." Does not make since.
While heavy wooed beams would char and retain strength, any substatial fire would consume a 1 1/2 thick pine member in very short order.

No, I am not affliated with Sureboard, nor have I used it, but it does look promising.

I have downloaded the ICBO Report and LA City Research Report for Sure-Board Series 200 Structural Panels. My Question is: How do I determine the fire rating of this panel, installed with gage metal wall stud framing? (I am not that familiar with the fire code, so bear with me). These reports say nothing about the fire rating.
