Overstrength and Nonbuilding Structures Not Similar to Buildings

[GearsNsparks]

I'm trying to figure out where (and if) Omega gets used when designing steel members and connections for non building structures not similar to buildings (Table 15.4-2). Does it only show up in the foundation design? A couple items for tanks and vessels are called out for section 15.7.3.a, but the remainder of the items have no pointers to any use for the Omega factor nor any seismic detailing requirements.

Thanks for any help.

Anchor Rods, collector elements....

Thanks Josh. Reviewing section 12.10.2: Collector elements, I interpret that to include any connections along the seismic load path need to be designed for overstrength factor. Does this also include the members connected by the connection elements?
