I can also confirm this table has been in this specification since or before 2005.
Having the vast majority of my onshore work come from a non-seismic region, even by ASCE-07 standards, no, this is generally deemed to not apply to my work.
Have I ever seen anyone else trying plugging 12" of displacement into CAESAR and back check against UTS? Also no. I've heard of it mentioned, although seemingly derisively.
What I would suggest, though, is that the following statement is our "get out of design specification hell" card.
Unless otherwise calculated, the minimum displacements in Table 15.7-1 shall be assumed.
My offshore work utilizes CSA-calculated accelerations.
