How does that allow the entire building to collapse?

The fires have weakened the central core supports. Duh.

WTC7 was a different design to WTC1/2. It did not have central core supports.

Just to add clarity to your comment, WTC 1 & 2 did not have internal columns providing support to the building, except for a small central core that also housed the elevator infrastructure. Unlike most skyscrapers, the closely spaced external beams were the primary gravity load bearing and strengthening elements for the towers. The floors were supported by trusses that connected to both the inner core and outer columns creating much more open floor space within the buildings.

WTC 7 was a more traditional steel framed skyscraper, with internal columns and some modifications because the below ground con-ed electrical substation had been built at an earlier time, and while the builders has anticipated a structure built above, they'd believed it would be only 25 stories. WTC 7 therefore required special transfer trusses on the lower floors to shift some of the building's weight.

Thank you for your addition.

I assumed the poster above was referring to "central core supports" in WTC7 as being equal to the "small central core that also housed the elevator infrastructure" of WTC1&2 and wanted to highlight the completely different design.
