The crane platform again, and "butt plates" on top of the elevator guide rail supports you and the perpetrators MISREPRESENT as "core columns".
Since your contention is that butt plates are not used for core columns, can you provide me with the proof that back up this claim of yours? Can you prove to me and everyone else that those butt/splice plates where NOT welded? Can you provide proof that those columns were not also welded together IN ADDITION to the butt/splice plates being welded?
If you can't provide the evidence to back your claim then you're just assuming. We ALL know how much you have gotten incorrect in the past concerning your "theory" when you either assume or base your claim on supposed "construction knowledge".
Prove to us how those columns are not strong enough to be core columns.
My bet is you can't.
