I have a 2-story building. It has a regular shape 40x54, 2-story, flexible roof diaphragm, rigid floor diaphragm. 2nd floor has R=6.5 for plywood shearwalls. 1st floor has R=3.5 for Ordinary Moment Frames of Steel.
When performing a vertical distribution from section 12.8.3, can I take the Vupper + the Vlower = Vtotal for my Fx force on each or do I take the CsW=Sds*I/R * W for the lowest R over the entire system for V?
I'll admit, I've done these before, but I'm a bit rusty as I usually don't do different systems vertically...
Thanks!
