How are you assigning elements into Omniclass which don’t clearly fit into a category? (At least not clear to me)
Interior or exterior concrete shear walls that aren’t part of a foundation enclosure - 21-02 10 10 10 Floor structure? Because they are providing lateral support to the floor?
Seismic bracing - same as above, under the same rationale?
I see that columns and beams supporting floors go under floor structure, and I assume we do the same for roof beams and columns under a roof? For columns that extend multiple floors to the roof, is the expectation to divide the geometry so the column on the top floor can be assigned to the roof?
In instances 1 & 2 i am generally grouping them with the upper level category (so Omniclass Level 3 21-02 10 10 Floor Construction instead of Level 4 21-02 10 10
10 Floor Structural Frame)
In instance 3, right now if they’re modelled as a single element, I’ll assign it to the class that’s the most suitable - not breaking it up. It may be worth it eventually, but it does not appear to yet.
I find the CSI Uniformat tables helpful in this regard. The standard also provides guidance for creation of new element codes if needed. As I understand, Uniformat was integrated in its entirety to Table 21, with A, B, C… being changed to 01, 02, 03…
