Metal strapping for timber shear wall
Metal strapping for timber shear wall
(OP)
We are designing a three-story timber frame building with shear walls. The architect has asked that we do not use plywood or osb sheathing for any of the walls for fire-rating reasons. It was proposed to use metal x-bracing straps secured to the studs and plates in lieu of sheathing.
Is this a common practice?
Can you direct me to any code, ICC, manufacturer, or other documents related to this?

Better to use some CS/CMST coiled strap over the studs, connedcted to the timberframe posts. The problem will be to develop the force in the strap to the end posts. Nailing to the studs will have no value here. Holssowns may or may not have to be added at the timber frame column depending on the dead loaqd to resist the overturning and your details.

I can send you the detail with capacities if you like..

In either case, the fire rating is only as good as the drywall cover.

Go to Strong-tie.com (sp??) and search on CS OR CSMT. It is there..
