Casey,

Wouldn’t this qualify as a “Vertical Combination”?  See CBC 1630.4.2

Subject: Steel SMRF on Conc. shearwall

 

I'm doing a project in high-end residential project in southern California, where I have a steel SMRF that is supported on the top of a 14 inch concrete Shearwall.

The question I have is that, does this concrete shearwall  need to be designed as an element supporting discontinuous system? (per 1630.8.2 & Table 16-L)

My own response to this is yes, however I'd appreciate second opinion.
