How far would column 79 have to move for what you are saying to happen?Except NIST didn't say the beams pushed the girder off the seat per se, and, as has been pointed out, the girder and the eastmost beams were cooling when the girder failed. At that time, it was the girder to the west of column 79 being heated. It seems more likely that it was resulting movement of column 79 back to the east that caused the ultimate dislodgement of girder A2001, not further absolute movement to the west of that girder. The relative heating and cooling of these elements is all readily apparent in the floor 13 heat maps that NIST provided. You have been stuck arguing against the same strawmill (a portmanteau of strawman and windmill that I coined just for you) for years.
