Basic Structural System - equipment pad

[Boiler106]

this is a dumb question, for sure, but does anyone know how i might describe the basic structural system on my design criteria section for a project that just consists of an equipment pad in a high seismic zone? Should i list it as "N/A, Ground Supported Slab"?

Rigid non structural component on ground support slab. ?

"N/A, slab only" if you want it specifically just for the pad.
For pad + equipment, maybe "Steel distributed mass cantilever structure" or "Inverted pendulum type structure" (pulling choices off Table 15.4-2 in ASCE 7-16).

Ground supported mat slab foundation?

Says the same thing as others, just different words.

I looked ( Guidelines for seismic evaluation and design of petrochemical facilities ) and the book uses the wording Ground Supported Non-Building Structure.
The foundation : Ground Supported Mat.
