Wood shearwall w/ offset
Wood shearwall w/ offset
(OP)
Hello,
I have a three story wood shearwall. The first and second levels line up, but the third story is offset horizontally about 4 feet out. I was thinking I could design the third floor diaphragm to cantilever out (or x braces in the floor) to pick up the shear, and possibly cantilever some beams out to pick up the point loads of the overturning force couple at the wall ends.
Any thoughts?

I think your concept is fine. Just trace the loads through the appropriate load paths, designing the members and connections for the forces induced.

What code are you using? If it's the UBC and seismic is an issue, look at 1630.8.2 and 1633.2.9
